Description

The grtRespondQueueRec( ) function responds to an event with a queue record. This function responds to the given event by sending a queue record to the channel on which the event occurred.

Example

#include "gfq.h"  
#include "genra.h"  
GRT_EVENT event;  
GFQRECORD qrec;  
int status, chan = 1;  
int grtAttributes = GRT_CALL_PENDING_ENABLE |  
GRT_CALL_PENDING_RESPONSE_ENABLE;  
/* initialize GRT pipes interface for fax channel 1 */  
status = grtInit(chan, chan, grtAttributes);  
if (status != GRT_SUCCESS)  
{  
   fprintf(stderr, "[%2d] grtInit failed, %d\n", chan, status);  
   return -1;  
}  
/* initialize, fill in, and submit queue record */  
...  
/* block for any event */  
while ((status = grtGetEvent(chan, chan, &event))     

== GRT_NO_EVENT)  
      Sleep(1000L);  
if (event.event_type == GRT_CALL_PENDING)  
{  
    /* respond to event */  
    /* perform ANSWER-RECEIVE-SEND operation (turn-around polling) */  
    if (status=grtRespondQueueRec(&event, &qrec))  
    {  
       fprintf(stderr, "[%2d] grtRespondQueueRec"      

               " failed, %d", event.chan, status);  
       return -1;  
    }
