realloc

Syntax

#include <cstdlib>
void *realloc( void *p, size_t s);

The function realloc() resizes a block created by malloc() or calloc(), and returns a pointer to the new memory region.

If the resize operation fails, realloc() returns NULL and leaves the old memory region intact.

Note:
realloc() does not have a corresponding operator in C++ - however, this is not required since the standard template library already provides the necessary memory management for most usages.
