bzero()
Set the first part of an object to null bytes
Synopsis:
#include <strings.h>
void bzero( void *dst,
size_t n );
Arguments:
- dst
- An existing object that you want to fill with zeroes.
- n
- The number of bytes to fill.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The bzero() function fills the first n bytes of the object pointed to by dst with zero (NUL) bytes.
Note:
This function is similar to the ANSI
memset()
function. New code should use the ANSI function.
Examples:
#include <stdlib.h>
#include <string.h>
int main( void )
{
char buffer[80];
bzero( buffer, 80 );
return EXIT_SUCCESS;
}
