gl_getctinfo( )

Description | Example

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

Description

The gl_getctinfo( ) function returns digital timeslot device information.

This function retrieves the device information related to a channel on a CP Fax SC board. On return from the function, the CT_DEVINFO structure contains the relevant information. The CT_DEVINFO structure is declared as follows:

typedef struct {

unsigned longct_prodid;

unsigned charct_devfamily

unsigned charct_devmode;

unsigned charct_nettype;

unsigned charct_busmode;

unsigned charct_busencoding;

unsigned charct_rfu[7];

} CT_DEVINFO;

The valid values for each member of the CT_DEVINFO structure are defined in gfsc.h.

The ct_prodid field contains a valid CP Fax product identification number for the device. The ct_devfamily field specifies the device family and will contain one of the following values:

CT_DFCP4	/* GammaLink CP -4 family */
CT_DFCP6	/* GammaLink CP -6 family */
CT_DFCP12	/* GammaLink CP -12 family */

The ct_devmode field is not valid for the CP Fax Series card.

The ct_nettype field may contain either of the following values:

CT_NTT1	/* T1 configuration */
CT_NTE1	/* E1 configuration */

CT_NTNONE

The ct_busmode field may contain either of the following values:

CT_BMPEB	/* PCM Expansion Bus architecture */
CT_BMSCBUS	/* SCbus architecture */

The ct_busencoding field may contain either of the following values:

CT_BEULAW	/*Mu-law PCM encoding */
CT_BEALAW	/*A-law PCM encoding */

Example

#include "gfsc.h"

CT_DEVINFO devinfop;

      .

      .

      .

status = gl_getctinfo(gl_devh, &devinfop)

if(status == 0)

   printf("Fax channel %d: product id=%d, bus mode=%d\n",   
          gl_devh, devinfop.ct_prodid, devinfop.ct_busmode);

else

   printf("Error %d\n", status);
