Description
The cc_GetCRN( ) function retrieves the call reference number for the event in
the event queue pointed to by evtdatap. The evtdatap pointer may be acquired
using the sr_getevtdatap( ) function in the Dialogic Standard Runtime Library
(SRL).
If the event is channel or time slot related and not call related, cc_GetCRN( )
returns a value < 0. If 0 is returned, the event is call related and the call reference
number will be in the location pointed to by crnp.
Parameter Description
crnp:
The address where the returned call reference number (CRN) is
stored.
evtdatap:
Pointer to the structure containing the event data block. The
pointer value is acquired using the SRL function
sr_getevtdatap( ).
