bstring(3) - Manual pages

NAME

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

library “libc”

#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 *dst, const void *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);

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.

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

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