2.13. gc_GetSigInfo( )

The gc_GetSigInfo( ) function gets the signaling information from the incoming ISDN message. To use the gc_GetSigInfo( ) function for a channel, the application needs to specify the size of the queue by calling the gc_SetParm( ) function and setting the RECEIVE_INFO_BUF to the desired size. Failure to set the size of RECEIVE_INFO_BUF will result in an error.

The User-to-User Information (UUI) data returned is application dependent. The user information return format for UUI is defined in the USRINFO_ELEM data structure, see Section4.4, USRINFO_ELEM. Use the USRINFO_ELEM structure to retrieve the UUI. Ensure that the size of the information buffer is large enough to hold the UUI string.

When using the DPNSS protocol, see the GlobalCall DPNSS ISDN Protocol Reference for protocol-related call scenarios, IEs and message types.
