If the ultimate goal is to write "N" ASCII NUL characters, then:
    #include <stdio.h>
    void
    putnul(n, f)
	register int n;
	register FILE *f;
    {
	while (--n >= 0)
	    (void)putc('\0', f);
    }

If the intermediate goal of getting a buffer of "N" zero-filled bytes
is also important, then look up calloc(3), bstring(3) and/or memory(3).
