ai_getxmitslot( )

Description | Example | See Also

Name:	int ai_getxmitslot(devh, sc_tsinfo)
Inputs:	int devh	specifies the valid device handle obtained when an audio input device is opened
	SC_TSINFO* sc_tsinfo	provides a pointer to the SCbus time slot information structure
Returns:	0 on success -1 on failure
Includes:	dxxxlib.h
Category:	Audio Input
Mode:	synchronous

Description

The ai_getxmitslot( ) function provides the SCbus time slot number of the audio input transmit channel. The SCbus timeslot information is contained in an SC_TSINFO structure.

Parameter	Description
devh	Specifies the valid device handle obtained when the audio input device is opened with the ai_open( ) function.
sc_tsinfo	Specifies a pointer to the SCbus timeslot information structure. The sc_numts member of the SC_TSINFO structure must be initialized with the number of SCbus time slots requested (1). The sc_tsarrayp member of the SC_TSINFO structure must be initialized with a valid pointer to a long variable. Upon successful return from the function, the long variable will contain the number of the SCbus time slot on which the audio input device transmits.

Example

#include <windows.h>          /* Include in Windows applications only */  
#include <stdio.h>  
#include <srllib.h>  
#include <dxxxlib.h>  
int main( )  
{  
   int         aidev;         /* Audio input device handle */  
   SC_TSINFO   sc_tsinfo;     /* Time slot information structure */  
   long        scts;          /* TDM bus time slot */  
   /* Open audio input device aiB1 */  
   if ((aidev = ai_open("aiB1")) < 0) {  
      /* process error */  
   }  
   /* Fill in the TDM bus time slot information */  
   sc_tsinfo.sc_numts = 1;  
   sc_tsinfo.sc_tsarrayp = &scts;  
   /* Get TDM bus time slot connected to transmit of audio input device */  
   if (ai_getxmitslot(aidev, &sc_tsinfo) < 0) {  
      /* process error */  
   }  
   else {  
      printf("%s is transmitting on TDM time slot %d", ATDV_NAMEP(aidev), scts);  
   }  
   /* Close audio input device */  
   if (ai_close(aidev) < 0) {  
      /* process error */  
   }  
    return 0;  
}
