BSTRING(3) FreeBSD 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 <string.h> int bcmp(const void *b1, const void *b2, size_t len); void bcopy(const void *src, void *dst, size_t len); void bzero(void *b, size_t len); void * memchr(const void *b, int c, size_t len); int memcmp(const void *b1, const void *b2, size_t len); void * memccpy(void * restrict dst, const void * restrict src, int c, size_t len); void * memcpy(void *dst, const void *src, size_t len); void * memmove(void *dst, const void *src, size_t len); void * memset(void *b, int c, size_t len); 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. SEE ALSO bcmp(3), bcopy(3), bzero(3), memccpy(3), memchr(3), memcmp(3), memcpy(3), memmove(3), memset(3) STANDARDS The functions memchr(), memcmp(), memcpy(), memmove(), and memset() conform to ISO/IEC 9899:1990 ("ISO C90").
