gl_getxmitslot( )

Description | Example

Name:	int gl_getxmitslot (int chan, SC_TSINFO *tsinfop)
Inputs:	int chan	Purpose: GDK channel. Range: 1 -- n, where n is the number of installed fax channels.
	SC_TSINFO* tsinfop	Purpose: Pointer to SCbus timeslots information. Range: N/A.
Returns:	0	Success.
	-1	Error.
Includes:	gfsc.h

Description

The gl_getxmitslot( ) function returns SCbus timeslot connected to digital timeslot transmit.

This function connects the external SCbus timeslot to the transmit of a channel on a CP Fax SC board. On return from the function, the SC_TSINFO structure contains the number of SCbus timeslots that are connected to the transmit of the local fax timeslot and a pointer to the array that contains the SCbus timeslots (between 1 and 1024). The SC_TSINFO structure is declared as follows:

typedef struct {

        unsigned longnumts;

        long*tsarray;

} SC_TSINFO;

This function fails if an invalid channel is specified. This function fails if called on a device in PEB mode.

NOTE:

A CP Fax SC fax channel can only transmit on one external SCbus timeslot. The SC_TSINFO structure is used to provide uniformity among SCbus timeslot access functions for all SCSA devices.

Example

#include "gfsc.h"  
SC_TSINFO   sc_tsinfo;   /* SCbus timeslot info

structure */  
long  scts; /* SCbus timeslot */  
int   devh1, status;  
devh1 = 1;  
sc_tsinfo.sc_numts = 1; /* always one timeslot */  
sc_tsinfo.sc_tsarrayp = &scts;  
status = gl_getxmitslot( devh1, &sc_tsinfo );  
if (status)  
{  
   fprintf(stderr, "gl_getxmitslot( ) error %d\n", status);  
   return (status);  
}  
else  
   fprintf(stdout,"chan %d is transmitting on timeslot %d\n",  
           devh1,scts);
