MEMSETPATTERN(3) BSD Library Functions Manual MEMSETPATTERN(3)

NAME
     mmeemmsseettppaatttteerrnn44, mmeemmsseettppaatttteerrnn88, mmeemmsseettppaatttteerrnn1166 - memset of a multi-
     byte pattern

LLIIBBRRAARRYY
     Standard C Library (libc, -lc)

SYNOPSIS
     ##iinncclluuddee <>

     void
     mmeemmsseettppaatttteerrnn44(void *b, const void *pattern4, sizet len);

     void
     mmeemmsseettppaatttteerrnn88(void *b, const void *pattern8, sizet len);

     void
     mmeemmsseettppaatttteerrnn1166(void *b, const void *pattern16, sizet len);

DESCRIPTION
     These are analogous to mmeemmsseett(), 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.

EEXXAAMMPPLLEESS
     The following example:

           char buf[10];

           memsetpattern4( buf, "1234", sizeof(buf) );

     will set the buffer to the value "1234123412".
