memmem(3) BSD Library Functions Manual memmem(3)
memmem -- locate a byte substring in a byte string
Standard C Library (libc, -lc)
#include <string.h> void * memmem(const void *big, size_t big_len, const void *little, size_t little_len);
The memmem() function locates the first occurrence of the byte string little in the byte string big.
If big_len is smaller than little_len, if little_len is 0, if big_len is 0 or if little occurs nowhere in big, NULL is returned; otherwise a pointer to the first character of the first occurrence of little is returned.
memmem() is a GNU extension.
The memmem() function first appeared in FreeBSD 6.0.
