memset_pattern8(3) [osx man page]

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". SEE ALSO
memset(3) HISTORY
These functions first appeared in Mac OS 10.5. Darwin October 14, 2005 Darwin

NAME
memccpy, memchr, memcmp, memcpy, memmem, memmove, memset -- byte string operations LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <string.h> 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 * memmem(const void *block, size_t blen, const void *pat, size_t plen); 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 nul bytes as the routines listed in string(3) do. See the specific manual pages for more information. SEE ALSO
memccpy(3), memchr(3), memcmp(3), memcpy(3), memmem(3), memmove(3), memset(3) STANDARDS
The functions memchr(), memcmp(), memcpy(), memmove(), and memset() conform to ANSI X3.159-1989 (``ANSI C89''). HISTORY
