BZERO(3)						   BSD Library Functions Manual 						  BZERO(3)

NAME

     bzero -- write zeroes to a byte string

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <strings.h>

     void
     bzero(void *s, size_t n);

DESCRIPTION

     The bzero() function writes n zeroed bytes to the string s.  If n is zero, bzero() does nothing.

SEE ALSO

     memset(3), swab(3)

HISTORY

     A bzero() function appeared in 4.3BSD.  Its prototype existed previously in <string.h> before it was moved to <strings.h> for IEEE Std
     1003.1-2001 (``POSIX.1'') compliance.

     bzero() was deprecated in IEEE Std 1003.1-2001 (``POSIX.1'') and removed in IEEE Std 1003.1-2008 (``POSIX.1'').

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.
