Query the signaling line identifiers for a specified trunk.
The signaling interface library (libsl.a).
#include <slsigpr.h> ... SL_RET_CODE sl_query_trunk_id ( int iVpackNo, SL_TRUNK_ID_ST * pslTrunkIdSt );
This subroutine returns the trunk id and all the channel ids for the specified pack. Each trunk has an associated string to identify it. Each channel has an associated string to identify it. These parameters are used to hold the exchange data link identifiers (see Exchange data link line identifiers). The organization of SL_TRUNK_ID_ST is shown in Figure 1.
