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 func-
     tions.

STANDARDS

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