sr_getevtdev( )

Description | Cautions | Applications | Example | See Also

Name:	long sr_getevtdev(ehandle)
Inputs:	unsigned long ehandle	· event handle returned by sr_waitevtEx( ), or zero if sr_waitevt( ) is used
Returns:	Dialogic device handle if successful
	-1 if no current event
Includes:	srllib.h
Type:	Event Data Retrieval function

Description

The sr_getevtdev( ) function returns the Dialogic device handle associated with the current event. If a timeout occurs while waiting for an event, this function returns SRL_DEVICE.

NOTE:

Information about the device handles that can be returned by this function can be found in the appropriate technology-specific Programmer's Guide.

Applications

Using sr_waitevt( )Pass a 0 (zero) parameter:
sr_getevtdev(0).
