<strong>REALLOC</strong>
==SYNOPSIS==
void * realloc(void * ptr, size_t cnt)
==DESCRIPTION==
<strong>Realloc</strong>() frees the block of memory at ptr, which
should have been obtained by a previous call to <strong>malloc</strong>(), <strong>calloc</strong>() or <strong>realloc</strong>(), then attempts to allocate
cnt bytes of dynamic memory, and if successful copies
the contents of the block of memory located at ptr into
the new block. At most, <strong>realloc</strong>() will copy the number
of bytes which were in the old block, but if the new
block is smaller, will only copy cnt bytes. If the
block could not be allocated, 0 is returned.
