Publib                                        C Programmer's Manual                                MEMFILL(3pub)

memfill  copies  consecutive  bytes  from  the  pattern  pat to consecutive bytes in the memory area buf,
       wrapping around in pat when its end is reached.  patsize is the size of the pattern, size is the size  of
       the memory area.  The pattern and the memory area must not be overlapping.

       To initialize an integer array one might do the following.

            int temp, array[1024];

            temp = 1234;
            memfill(array, sizeof(array), &temp, sizeof(temp));

memfill returns its first argument.
