|Example: realloc||Return Values||Memory Allocation Functions|
Reallocates (adjusts the size of) a block of memory.
void *realloc( void *mem_address, size_t size);
|mem_address||The name of the block of memory whose size is changed.|
|size||The size in bytes of the block of memory requested.|
Returns a void * type pointer to the allocated space. If the system could not allocate the requested block of memory or if any of the parameters was 0, returns a NULL pointer.
For realloc details, refer to your C language documentation.
