Description
The cc_GetSigInfo( ) function gets the signaling information of an incoming
message. The library uses evtdatap to retrieve the associated signaling
information elements (IEs) and puts the information in the queue.
In order to use the cc_GetSigInfo( ) function for a channel, the application needs
to specify the size of the queue by calling the cc_SetParm( ) function and setting
the RECEIVE_INFO_BUF to the desired size.
Parameter Description
valuep:
Points to the buffer where the call information will be stored.
info_id:
Specifies the type of signaling information to be retrieved (see
Table 23 below).
evtdatap:
Points to the event data block. This pointer may be acquired by
using sr_getevtdatap( ), an element of the Dialogic Standard
Runtime Library (SRL).
The following table provides definitions of possible info_id parameters.
