#include <string.h>

memmem
(const
void *block, size_t
blen, const void
*pat, size_t
plen);
memmem
() function locates the first occurrence of
the binary string pat of size plen
bytes in the byte string block of size
blen bytes.
memmem
() function returns a pointer to the substring
located, or NULL
if no such substring exists within
block.
If plen is zero, block is returned, i.e. a zero length pat is deemed to match the start of the string, as with strstr(3).
memmem
() function is not currently standardized.
However, it is meant to be API compatible with functions in
FreeBSD and Linux.
memmem
() first appeared in the Free Software
Foundation's glibc library.
