一个很好的unix网络编程框架

#include "../etcp.h"

/* udp_client - set up a UDP client */
SOCKET udp_client( char *hname, char *sname,
	struct sockaddr_in *sap )
{
	SOCKET s;

	set_address( hname, sname, sap, "udp" );
	s = socket( AF_INET, SOCK_DGRAM, 0 );
	if ( !isvalidsock( s ) )
		error( 1, errno, "socket call failed" );
	return s;
}
