readme_broadcastget

这里包含了风河vxworks系统中的官方例程的C源代码

FILE LIST -
             broadcastGet.c

DESCRIPTION -
	     Demo for getting the broadcast message. It also demonstrates the 
             usage of SIOCGIFCONF ioctl option. This SIOCGIFCONF ioctl 
             option is not needed for broadcasting.


RUNNING DEMO -
   	     Run broadcastGet task on one VxWorks system as follows
	     before starting the broadcastSend task from another VxWorks 
             system in the same physical network. The other half of 
             the demonstration is in broadcastSend.c.

	     Port number should be greater than 5000 for user applications.

TESTED ON - Host/Target : Solaris 2.5.1 / mv1604
	    VxWorks     : 5.3.1
				   
EXAMPLE COMPILE LINE - (use the Makefile in the BSP dir.)
   	    make CPU=PPC604  broadcastGet.o
