MEMMEM(3)						   BSD Library Functions Manual 						 MEMMEM(3)

NAME

     memmem -- locate substring in byte string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     void *
     memmem(const void *block, size_t blen, const void *pat, size_t plen);

DESCRIPTION

     The memmem() function locates the first occurrence of the binary string pat of size plen bytes in the byte string block of size blen bytes.

RETURN VALUES

     The 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).

SEE ALSO

     bm(3), memchr(3), strchr(3), strstr(3)

STANDARDS

     The memmem() function is not currently standardized.  However, it is meant to be API compatible with functions in FreeBSD and Linux.

HISTORY

     memmem() first appeared in the Free Software Foundation's glibc library.
