Function Documentation

void* explain_realloc_on_error ( void *  ptr,
size_t  size 
)

The explain_realloc_on_error function is used to call the realloc(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_realloc(3) function.

This function is intended to be used in a fashion similar to the following example:

 void *new_ptr = explain_realloc_on_error(ptr, size);
 if (!new_ptr)
 {
     ...cope with error
     ...no need to print error message
 }
Parameters:
ptrThe ptr, exactly as to be passed to the realloc(3) system call.
sizeThe size, exactly as to be passed to the realloc(3) system call.
Returns:
The value returned by the wrapped realloc(3) system call.
