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".
