  • convert pointer to pointer to void pointer

    - by FihopZz
    When I'm learning to use qsort to sort an array of string, there is a question puzzled me. For example, to sort the following s char *s[] = { "Amit", "Garima", "Gaurav", "Vaibhav" }; To use the qsort, you must provide a comparison function like the following function cstring_cmp I guess in the qsort function, the type of parameter to be passed to the function cstring_cmp is char**. How to convert a char** to a void*? Why can we convert a char** to a void*? int cstring_cmp(const void *a, const void *b) { const char **ia = (const char **)a; const char **ib = (const char **)b; return -strcasecmp(*ia, *ib); /* return the negative of the normal comparison */ }

  • Why does void in C mean not void?

    - by Naftuli Tzvi Kay
    In strongly-typed languages like Java and C#, void (or Void) as a return type for a method seem to mean: This method doesn't return anything. Nothing. No return. You will not receive anything from this method. What's really strange is that in C, void as a return type or even as a method parameter type means: It could really be anything. You'd have to read the source code to find out. Good luck. If it's a pointer, you should really know what you're doing. Consider the following examples in C: void describe(void *thing) { Object *obj = thing; printf("%s.\n", obj->description); } void *move(void *location, Direction direction) { void *next = NULL; // logic! return next; } Obviously, the second method returns a pointer, which by definition could be anything. Since C is older than Java and C#, why did these languages adopt void as meaning "nothing" while C used it as "nothing or anything (when a pointer)"?

  • How to implement an interface member that returns void in F#

    - by Drew Noakes
    Imagine the following interface in C#: interface IFoo { void Bar(); } How can I implement this in F#? All the examples I've found during 30 minutes of searching online show only examples that have return types which I suppose is more common in a functional style, but something I can't avoid in this instance. Here's what I have so far: type Bar() = interface IFoo with member this.Bar = void Fails with FS0010: Unexpected keyword 'void' in expression.

  • Call a void* as a function without declaring a function pointer

    - by ToxIk
    I've searched but couldn't find any results (my terminology may be off) so forgive me if this has been asked before. I was wondering if there is an easy way to call a void* as a function in C without first declaring a function pointer and then assigning the function pointer the address; ie. assuming the function to be called is type void(void) void *ptr; ptr = <some address>; ((void*())ptr)(); /* call ptr as function here */ with the above code, I get error C2066: cast to function type is illegal in VC2008 If this is possible, how would the syntax differ for functions with return types and multiple parameters?

  • What does this mean: warning: converting from ‘void (ClassName::*)()’ to ‘void (*)()’

    - by Brendan Long
    I have a member function in a class that has a callback, but the callback isn't strictly neccessary, so it has a default callback, which is empty. It seems to work fine, but I get an annoying warning: warning: converting from ‘void (ClassName::*)()’ to ‘void (*)()’ I'm trying to figure out what it means and how to turn it off (or fix it if I really am doing something wrong). Here's some simple code: class ClassName{ public: void doSomething(void (*callbackFunction)() = (void(*)()) &ClassName::doNothing){ callbackFunction(); } void doNothing(){} }; int main(){ ClassName x; x.doSomething(); return 0; } Note: If I do this (without explicitly casting it as a void(*)()): void doSomething(void (*callbackFunction)() = &ClassName::doNothing) I get this: main.cpp:3: error: default argument for parameter of type ‘void (*)()’ has type ‘void (ClassName::*)()’

  • SWIG: C++ to C#, pointer to pointer marshalling.

    - by CaRT
    I have some legacy code I want to port to C#. I cannot modify the C++ code, I just have to make do with what I'm given. So, the situation. I'm using SwIG, and I came across this function: void MarshalMe(int iNum, FooClass** ioFooClassArray); If I ran SWIG over this, it wouldn't know what to do with the array, so it will create a SWIGTYPE_p_pFooClass. Fair enough! C# code for this would look like void MarshalMe(int iNum, SWIGTYPE_p_p_FooClass ioFooClassArray); // Not ideal! There are some techniques for marshalling this kind of code correctly, so I tried a few of them: %typemap(ctype) FooClass** "FooClass**" %typemap(cstype) FooClass** "FooClass[]" %typemap(imtype, inattributes="[In, Out, MarshalAs(UnmanagedType.LPArray)]") FooClass** "FooClass[]" %typemap(csin) FooClass** "$csinput" %typemap(in) FooClass** "$1 = $input;" %typemap(freearg) FooClass** "" %typemap(argout) FooClass** "" This effectively creates a nicer signature: void MarshalMe(int iNum, FooClass[] ioFooClassArray); // Looks good! Would it work? However, when I try to run it, I get the following error: {"Exception of type 'System.ExecutionEngineException' was thrown."} Any ideas about the actual typemap?

  • How to use void*

    - by Rondogiannis Aristophanes
    I am imlementing a simple merge function and I have got stuck, as the compiler gives me errors that I cannot explain.

  • What do I return if the return type of a method is Void? (Not void!)

    - by DR
    Due to the use of Generics in Java I ended up in having to implement a function having Void as return type: public Void doSomething() { //... } and the compiler demands that I return something. For now I'm just returning null, but I'm wondering if that is good coding practice... I've also tried Void.class, void, Void.TYPE, new Void(), no return at all, but all that doesn't work at all. (For more or less obvious reasons) (See this answer for details) So what am I supposed to return if the return type of a function is Void? What's the general use of the Void class? EDIT: Just to spare you the downvotes: I'm asking about V?oid, not v?oid. The class Void, not the reserved keyword void.

First of all here is the code ViewController.h #import <UIKit/UIKit.h> @interface ViewController : UIViewController { IBOutlet UIWebView *webview; IBOutlet UIActivityIndicatorView *active; UIAlertView *alert_start; UIAlertView *alert_error; } -(IBAction)tele_button:(id)sender; -(IBAction)mail_button:(id)sender; -(IBAction)web_button:(id)sender; -(IBAction)news_button:(id)sender; @end ViewController.m #import "ViewController.h" @implementation ViewController - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } #pragma mark - View lifecycle - (void)viewDidLoad { [super viewDidLoad]; //Stop Bounce for WebView for (id subview in webview.subviews) if ([[subview class] isSubclassOfClass: [UIScrollView class]]) ((UIScrollView *)subview).bounces = NO; //First Start Alert [alert_start show]; NSLog(@"first alert"); NSString *start_alert = [[NSUserDefaults standardUserDefaults] objectForKey:@"alert_start"]; if(start_alert == nil) { [[NSUserDefaults standardUserDefaults] setValue:@"1" forKey:@"alert_start"]; [[NSUserDefaults standardUserDefaults] synchronize]; UIAlertView *alert_start = [[UIAlertView alloc] initWithTitle:@"iOptibelt" message:@"On some points this application need a internet connection." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert_start show]; [alert_start release]; } // Do any additional setup after loading the view, typically from a nib. [webview loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"home-de" ofType:@"html"]isDirectory:NO]]]; NSLog(@"webview fertig"); } -(void)webViewDidStartLoad:(UIWebView *) webview { [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [active startAnimating]; NSLog(@"lade"); } -(void)webViewDidFinishLoad:(UIWebView *) webview { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; [active stopAnimating]; NSLog(@"fertig"); } -(void)webView: (UIWebView *) webview didFailLoadWithError:(NSError *)error{ NSLog(@"lade error"); UIAlertView *alert_error = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Can't connect. Please check your internet Connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert_error show]; [alert_error release]; }; - (IBAction)tele_button:(id)sender{ NSLog(@"it's connected!"); //Local HTML Call Button NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"phone" ofType:@"html"]isDirectory:NO]]; [webview loadRequest:theRequest]; } - (IBAction)mail_button:(id)sender{ NSLog(@"it's connected!"); //Mail App Mail Button [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]]; } - (IBAction)web_button:(id)sender{ NSLog(@"it's connected!"); //Local HTML Button NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString: @"http://optibelt.com"]]; [webview loadRequest:theRequest]; } - (IBAction)news_button:(id)sender{ NSLog(@"it's connected!"); //local Home Button NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"home-de" ofType:@"html"]isDirectory:NO]]; [webview loadRequest:theRequest]; } - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; } - (void)viewDidDisappear:(BOOL)animated { [super viewDidDisappear:animated]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } @end At last my 3. -(void) does not work and i ve no more idea what could be the problem.... -(void)webViewDidStartLoad:(UIWebView *) webview { [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [active startAnimating]; NSLog(@"lade"); } -(void)webViewDidFinishLoad:(UIWebView *) webview { [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; [active stopAnimating]; NSLog(@"fertig"); } -(void)webView: (UIWebView *) webview didFailLoadWithError:(NSError *)error{ NSLog(@"lade error"); UIAlertView *alert_error = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Can't connect.

  • Void in main and keeping Dos program from dying

    - by TimothyTech
    Alright, so im using bloodshed complier, first thing i should note is im using a 2001 edition C++ for the aboslute beginner, was there any changes to C++ since 2001 that would effect the validity of this book? i ask because i know php has php5 and now php6 but i havent seen any C++3. now for the reason i asked that, in this code it uses, void main (void) why would i want an arguement to be void? what does this do. But when i run the " void main (void) in my compiler it says that main must have a "int" before it. so i cant have "void" main (void); also, once the code runs through, as long as there isnt a "cin" the program closes. is this normal behavior, is there a better way to stop this besides making a cin at the end of my program.

  • Undefined symbols after installing new xcode 3.2.3 build

    - by toofah
    I want to move to the new XCode 3.2.3 GM Seed build for development, but when I bring up my project I get 'base sdk missing' because my project is set to use iPhone SDK 3.0. If I change 'base SDK' to iPhone 3.2 or 4.0 and then compile I get a lot of errors that I don't understand. I dumped a few of them below. Can anyone tell me what I am missing? Also, can someone confirm that if I choose 'base sdk' of iPhone 3.2 or 4.0 that I can still choose 'target device' of iPhone 3.0 and not force my customers to install the new SDK. I really don't want to be the app that forces my customers to upgrade their OS. Thanks!

  • Void pointers in C

    - by avd
    I have written this qsort: void qsort(void *a[],int low,int high, int (*compare)(void*,void*)); When I call this on char *strarr[5]; It says invalid conversion from char** to void**. Why this is wrong? This is the code:http://codepad.org/Flfm2zAE

  • How to get rid of void-pointers.

    - by Patrick
    I inherited a big application that was originally written in C (but in the mean time a lot of C++ was also added to it). Because of historical reasons, the application contains a lot of void-pointers. Before you start to choke, let me explain why this was done. The application contains many different data structures, but they are stored in 'generic' containers. Nowadays I would use templated STL containers for it, or I would give all data structures a common base class, so that the container can store pointers to the base class, but in the [good?] old C days, the only solution was to cast the struct-pointer to a void-pointer. Additionally, there is a lot of code that works on these void-pointers, and uses very strange C constructions to emulate polymorphism in C. I am now reworking the application, and trying to get rid of the void-pointers. Adding a common base-class to all the data structures isn't that hard (few days of work), but the problem is that the code is full of constructions like shown below. This is an example of how data is stored: void storeData (int datatype, void *data); // function prototype ... Customer *myCustomer = ...; storeData (TYPE_CUSTOMER, myCustomer); This is an example of how data is fetched again: Customer *myCustomer = (Customer *) fetchData (int datatype, char *key); I actually want to replace all the void-pointers with some smart-pointer (reference-counted), but I can't find a trick to automate (or at least) help me to get rid of all the casts to and from void-pointers. Any tips on how to find, replace, or interact in any possible way with these conversions?

  • Void pointer values comparing C++

    - by user2962977
    My actual question is it really possible to compare values contained in two void pointers, when you actually know that these values are the same type? For example int. void compVoids(void *firstVal, void *secondVal){ if (firstVal < secondVal){ cout << "This will not make any sense as this will compare addresses, not values" << endl; } } Actually I need to compare two void pointer values, while outside the function it is known that the type is int. I do not want to use comparison of int inside the function. So this will not work for me as well: if (*(int*)firstVal > *(int*)secondVal) Any suggestions? Thank you very much for help!

  • Problem using void pointer as a function argument

    - by Nazgulled
    Hi, I can't understand this result... The code: void foo(void * key, size_t key_sz) { HashItem *item = malloc(sizeof(HashItem)); printf("[%d]\n", (int)key); ... item->key = malloc(key_sz); memcpy(item->key, key, key_sz); } void bar(int num) { foo(&num, sizeof(int)); } And I do this call: bar(900011009); But the printf() output is: [-1074593956] I really need key to be a void pointer, how can I fix this?

  • Need for prefixing a function with (void)...

    - by puffadder
    Hi All, I recently came across a rather unusual coding convention wherein the call for a function returning "void" is prefixed with (void). e.g. (void) MyFunction(); Is it any different from the function call like: MyFunction(); Has it got any advantage or is it yet another needless but there coding convention of some sort?

  • C Class Instance from Void Pointer using Ctypes

    - by g.d.d.c
    I've got a C DLL that exposes a handful of methods that return void pointers to a Class like so: void *GetLicense() { static AppLicenseImpl ipds_; return (void *) &ipds_; } In C++, after loading the DLL, I'd do this to work with it: typedef void *(* FPGetLicense)(); GetLicense_ = (FPGetLicense)GetAddress("GetLicense"); license_ = (AppLicense *) GetLicense_(); license_->GetApplicationStatus(); // Load data so that other calls don't fail I can't figure out how to parallel that in Python. This gets me the pointer: d = ctypes.cdll.LoadLibrary('license.dll') d.GetLicense.restype = ctypes.c_void_p p = d.GetLicense() # returns ptr loc, something like 8791433660848L But I obviously can't call p.GetApplicationStatus() in Python. Does anyone have a suggestion on how I'd instantiate that Class the rest of the way in Python so that I can call GetApplicationStatus()?

  • C Programming: malloc() for a 2D array (using pointer-to-pointer)

    - by vikramtheone
    Hi Guys, yesterday I had posted a question: How should I pass a pointer to a function and allocate memory for the passed pointer from inside the called function? From the answers I got, I was able to understand what mistake I was doing. I'm facing a new problem now, can anyone help out with this? I want to dynamically allocate a 2D array, so I'm passing a Pointer-to-Pointer from my main() to another function called alloc_2D_pixels(...), where I use malloc(...) and for(...) loop to allocate memory for the 2D array. Well, after returning from the alloc_2D_pixels(...) function, the pointer-to-pointer still remains NULL, so naturally, when I try accessing or try to free(...) the Pointer-to-Pointer, the program hangs. Can anyone suggest me what mistakes I'm doing here? Help!!! Vikram SOURCE: main() { unsigned char **ptr; unsigned int rows, cols; if(alloc_2D_pixels(&ptr, rows, cols)==ERROR) // Satisfies this condition printf("Memory for the 2D array not allocated"); // NO ERROR is returned if(ptr == NULL) // ptr is NULL so no memory was allocated printf("Yes its NULL!"); // Because ptr is NULL, with any of these 3 statements below the program HANGS ptr[0][0] = 10; printf("Element: %d",ptr[0][0]); free_2D_alloc(&ptr); } signed char alloc_2D_pixels(unsigned char ***memory, unsigned int rows, unsigned int cols) { signed char status = NO_ERROR; memory = malloc(rows * sizeof(unsigned char** )); if(memory == NULL) { status = ERROR; printf("ERROR: Memory allocation failed!"); } else { int i; for(i = 0; i< cols; i++) { memory[i] = malloc(cols * sizeof(unsigned char)); if(memory[i]==NULL) { status = ERROR; printf("ERROR: Memory allocation failed!"); } } } // Inserted the statements below for debug purpose only memory[0][0] = (unsigned char)10; // I'm able to access the array from printf("\nElement %d",memory[0][0]); // here with no problems return status; } void free_2D_pixels(unsigned char ***ptr, unsigned int rows) { int i; for(i = 0; i < rows; i++) { free(ptr[i]); } free(ptr); }

  • C - Complicated pointer declarations - help understanding

    - by Emmel
    In my burgeoning new self-education in the C language, I've come across a set of declarations that I do not understand how to read. I'd love for someone to break these down. I'll explain at the bottom where I got these examples from. 1. char (*(*x())[])() "x: function returning pointer to array[] of pointer to function returning char" - huh? 2. char (*(*x[3])())[5] "x: array[3] of pointer to function returning pointer to array[5] of char" - come again? 3. char **argv This I understand. "Pointer to pointer to char." But what I don't understand is -- what's the use case for a pointer to a pointer? Follow-up question: does anyone every use declarations this complex or is this just academic fun on the part of the authors of the examples I got this from? These examples are from section 5.12 of the K&R book. This is the first time I'm genuinely stumped by an explanation, in an otherwise well-written classic. Thanks.

  • Pointer incrementing query

    - by Craig
    I have been looking at this piece of code, and it is not doing what I expect. I have 3 globals. int x, y, *pointer, z; Inside of main I declare them. x = 10; y = 25; pointer = &x; now at this point &x is 0x004A144 &y is 0x004A138 pointer is pointing to 0x004A144 Now when I increment: y = *++pointer; it points to 0x004A148, this is the address y should be at shouldn't it? The idea is that incrementing the pointer to 'x' should increment it to point at y, but it doesn't seem to want to declare them in in order like I expect. If this a VS2005 / 2008 problem? Or maybe an Express problem? This isn't really homework, as I have done it a couple of years ago but I was revising on my pointer stuff and I tried this again. But this time I am getting unexpected results. Does anyone have opinions on this? *UPDATE sorry should be more clear, 'thought' on declaration 'y' should be at 148, and that incrementing the pointer pointing to x should increment 'pointer' to 148 (which it does), but that isn't where y is. Why isn't y declaring where it should be.

  • Dereferencing the null pointer

    - by zilgo
    The standard says that dereferencing the null pointer leads to undefined behaviour. But what is "the null pointer"? In the following code, what we call "the null pointer": struct X { static X* get() { return reinterpret_cast<X*>(1); } void f() { } }; int main() { X* x = 0; (*x).f(); // the null pointer? (1) x = X::get(); (*x).f(); // the null pointer? (2) x = reinterpret_cast<X*>( X::get() - X::get() ); (*x).f(); // the null pointer? (3) (*(X*)0).f(); // I think that this the only null pointer here (4) } My thought is that dereferencing of the null pointer takes place only in the last case. Am I right? Is there difference between compile time null pointers and runtime according to C++ Standard?
