This document is a Mac OS X manual page. Manual pages are a command-line technology for providing documentation. You can view these manual pages locally using the man(1) command. These manual pages come from many different sources, and thus, have a variety of writing styles. For more information about the manual page format, see the manual page for manpages(5). |
MEMSET_PATTERN(3) BSD Library Functions Manual MEMSET_PATTERN(3) NAME memset_pattern4, memset_pattern8, memset_pattern16 -- memset of a multi-byte multibyte 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 |
