memset_pattern3
Memset of a multi-byte pattern
Usage
#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);
Library
Standard C Library (libc, -lc)
Overview
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".
