This document is a Mac OS X manual page. Manual pages are a command-line technology for providing documentation. You can view these manual pages locally using the man(1) command. These manual pages come from many different sources, and thus, have a variety of writing styles. For more information about the manual page format, see the manual page for manpages(5). |
BSTRING(3) BSD Library Functions Manual BSTRING(3) NAME bcmp, bcopy, bzero, memccpy, memchr, memcmp, memcpy, memmove, memset --byte -byte 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.
