/* File : memset.c
|
|
Author : Richard A. O'Keefe.
|
|
Updated: 25 May 1984
|
|
Defines: memset()
|
|
|
|
memset(dst, chr, len)
|
|
fills the memory area dst[0..len-1] with len bytes all equal to chr.
|
|
The result is dst. See also bfill(), which has no return value and
|
|
puts the last two arguments the other way around.
|
|
|
|
Note: the VAX assembly code version can only handle 0 <= len < 2^16.
|
|
It is presented for your interest and amusement.
