Describe the bug

nmap/nping/utils_net.cc

Lines 496 to 509 in fd80921

	int getNetworkInterfaceName(struct sockaddr_storage *dst, char *dev){
	struct route_nfo rnfo;
	struct sockaddr_storage src;
	bool result=false;
	if(dev==NULL)
	nping_fatal(QT_3, "getNetworkInterfaceName(): NULL value supplied.");
	memset(&rnfo, 0, sizeof(struct route_nfo) );
	memset(&src, 0, sizeof(struct sockaddr_in) );
	result=route_dst(dst, &rnfo, NULL, NULL);
	if( result == false )
	return OP_FAILURE;
	strncpy( dev, rnfo.ii.devname, 16 );
	return OP_SUCCESS;
	} /* End of getSourceAddress() */

What's the point of defining

struct sockaddr_storage src

then filling with 16 zeros

memset(&src, 0, sizeof(struct sockaddr_in) );

and not using as 4th parameter in:

result=route_dst(dst, &rnfo, NULL, NULL);
