/* xmemdup.c -- Duplicate a memory buffer, using xcalloc.
This trivial function is in the public domain.
Jeff Garzik, September 1999. */
@deftypefn Replacement void* xmemdup (void *@var{input}, size_t @var{copy_size}, size_t @var{alloc_size})
Duplicates a region of memory without fail. First, @var{alloc_size} bytes
are allocated, then @var{copy_size} bytes from @var{input} are copied into
it, and the new memory is returned. If fewer bytes are copied than were
allocated, the remaining memory is zeroed.
