[xen-users]event channel

["Sanjib Kumar Das" <Sanjib.Kumar.Das@xxxxxxxxxxxx>]

Hi all,

Can somebody please send me a C code to setup an event channel between two domains and sending a simple mssg through the channel.
I'm facing problems in writing such a code.I want to use the hypercalls of Xen in my code but I'm unable.
I'm facing problem if I include the event_channel.h header file:
My code snippet looks like:
#include<stdio.h>
#include<xen/event_channel.h>
int main(){
     int dom1=0;
     int dom2=1;
     int port1=3500;
     int port2=3500;
     //bind_interdomain(dom1,dom2,port1,port2);
     return 0;
}

I have commented out the bind-interdomain() call.Still facing the following errors on compilation:

/usr/include/xen/event_channel.h:12: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'evtchn_port_t'
/usr/include/xen/event_channel.h:25: error: expected specifier-qualifier-list before 'domid_t'
/usr/include/xen/event_channel.h:42: error: expected specifier-qualifier-list before 'domid_t'
/usr/include/xen/event_channel.h:59: error: expected specifier-qualifier-list before 'uint32_t'
/usr/include/xen/event_channel.h:74: error: expected specifier-qualifier-list before 'uint32_t'
/usr/include/xen/event_channel.h:89: error: expected specifier-qualifier-list before 'uint32_t'
/usr/include/xen/event_channel.h:102: error: expected specifier-qualifier-list before 'evtchn_port_t'
/usr/include/xen/event_channel.h:112: error: expected specifier-qualifier-list before 'evtchn_port_t'
/usr/include/xen/event_channel.h:126: error: expected specifier-qualifier-list before 'domid_t'
/usr/include/xen/event_channel.h:163: error: expected specifier-qualifier-list before 'evtchn_port_t'
/usr/include/xen/event_channel.h:174: error: expected specifier-qualifier-list before 'evtchn_port_t'
/usr/include/xen/event_channel.h:178: error: expected specifier-qualifier-list before 'uint32_t'

please help me figure out the problem.If possible please send me a sample code to setup an event channel between two domains and also specify the  header files to be included.

Thanks in advance.
