• Adding a wrapper to an overloaded function

  - by Cev

  Say you had a timestamp function and then wanted to create a new function to combine your timestamp and Console.WriteLine(), e.g. public static void Write(string msg) { WriteTimeStamp(); Console.WriteLine( msg ); } But the WriteLine() method has 18 or so overloads, which will not be reflected in the signature of the wrapper function. How would you have the wrapper take non-strings and pass them on to WriteLine()?

• Using macro to check null values

  - by poliron

  My C code contains many functions with pointers to different structs as parameters which shouldn't be NULL pointers. To make my code more readable, I decided to replace this code: if(arg1==NULL || arg2==NULL || arg3==NULL...) { return SOME_ERROR; } With that macro: NULL_CHECK(arg1,arg2,...) How should I write it, if the number of args is unknown and they can point to different structs?(I work in C99)
