bzero(3C)                        DG/UX 5.4.2                       bzero(3C)


NAME
       bzero - zero a portion of memory

SYNOPSIS
       int bzero(), length;
       char *ptr;
       ...
       bzero(ptr, length);

   where:
       ptr     A pointer to the area to clear
       length  The number of bytes set to zero

DESCRIPTION
       The bzero function fills a specified memory area with zeros.  The
       size of the area of memory is equal to length.

       This function comes from the University of California Berkeley UNIX
       (BSD) system.

RETURNS
       The bzero function returns no value.

EXAMPLE
       /* Program test for the bzero() function */

       #include <stdio.h>

       int bzero();
       char buf[80] = "abcdef";

       main() {
           printf("buf = '%s'\n", buf);
           bzero(buf, sizeof(buf));
           printf("buf = '%s'\n", buf);
           return 0;
       }

       A call to this program generates the output

       buf = 'abcdef'
       buf = ''
