typedef to store pointers in C
- by seriouslion
The Size of pointer depends on the arch of the machine.
So
sizeof(int*)=sizeof(int) or sizeof(int*)=sizeof(long int)
I want to have a custom data type which is either int or long int depending on the size of pointer.
I tried to use macro #if, but the condition for macros does not allow sizeof operator.
Also when using if-else, typedef is limited to the scope of if.
if((sizeof(int)==sizeof(int *)){
typedef int ptrtype;
}
else{
typedef long int ptrtype;
}
//ptrtype not avialble here
Is there any way to define ptrtype globally?
