TSPI_lineGetCallAddressID

  • Article

This function retrieves the address identifier for the indicated call.

LONG TSPIAPI TSPI_lineGetCallAddressID(
  HDRVCALL hdCall, 
  LPDWORD lpdwAddressID 
);

Parameters

  • hdCall
    Service provider's handle to the call whose address identifier is to be retrieved. The call state of hdCall can be any state.
  • lpdwAddressID
    Pointer to a DWORD into which the service provider writes the call's address identifier.

Return Values

Returns zero if the function succeeds or an error number if an error occurs. The following table shows the return values for this function.

Value Description
LINEERR_NOMEM Not enough memory is available.
LINEERR_OPERATIONFAILED The operation failed.
LINEERR_OPERATIONUNAVAIL The operation is unavailable.
LINEERR_RESOURCEUNAVAIL The resource is unavailable.

Remarks

If the service provider models lines as "pools" of channel resources and does inverse multiplexing of a call over several address identifiers, it should consistently choose one of these address identifiers as the primary identifier reported by this function and in the LINECALLINFO data structure.

This function has no direct correspondence at the TAPI level. It gives TAPI sufficient information to implement the lineGetNewCalls function invoked with the LINECALLSELECT_ADDRESS option.

Requirements

OS Versions: Windows CE 3.0 and later.
Header: Tapicomn.h.
Link Library: Coredll.lib.
