BSTRING(3)               BSD Library Functions Manual               BSTRING(3)

NAME
     bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memmove, memset -- byte string operations

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <strings.h>

     int
     bcmp(const void *s1, const void *s2, size_t n);

     void
     bcopy(const void *s1, void *s2, size_t n);

     void
     bzero(void *s, size_t n);

     #include <string.h>

     void *
     memccpy(void *restrict s1, const void *restrict s2, int c, size_t n);

     void *
     memchr(const void *s, int c, size_t n);

     int
     memcmp(const void *s1, const void *s2, size_t n);

     void *
     memcpy(void *restrict s1, const void *restrict s2, size_t n);

     void *
     memmove(void *s1, const void *s2, size_t n);

     void *
     memset(void *s, int c, size_t n);

DESCRIPTION
     These functions operate on variable length strings of bytes.  They do not check for terminating null
     bytes, as the routines listed in string(3) do.

     See the specific manual pages for more information.

LEGACY SYNOPSIS
     #include <string.h>

     The include file <string.h> is necessary and sufficient for all functions.

SEE ALSO
     bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3),
     compat(5)

STANDARDS
     The functions memchr(), memcmp(), memcpy(), memmove(), and memset() conform to ISO/IEC 9899:1990
     (``ISO C90'').

HISTORY
     The functions bzero() and memccpy() appeared in 4.3BSD; the functions bcmp(), bcopy(), appeared in
     4.2BSD.
