MEMSET_PATTERN(3)					   BSD Library Functions Manual 					 MEMSET_PATTERN(3)

NAME

     memset_pattern4, memset_pattern8, memset_pattern16 -- memset of a multi-byte pattern

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <string.h>

     void
     memset_pattern4(void *b, const void *pattern4, size_t len);

     void
     memset_pattern8(void *b, const void *pattern8, size_t len);

     void
     memset_pattern16(void *b, const void *pattern16, size_t len);

DESCRIPTION

     These are analogous to memset(), except that they fill memory with a replicated pattern either 4, 8, or 16 bytes long.  b points to a buffer
     of size len bytes which is to be filled.  The second parameter points to the pattern.  If the buffer length is not an even multiple of the
     pattern length, the last instance of the pattern will be truncated.  Neither the buffer nor the pattern pointer need be aligned.

EXAMPLES

     The following example:

	   char buf[10];

	   memset_pattern4( buf, "1234", sizeof(buf) );

     will set the buffer to the value "1234123412".

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.
