This function enables an application to obtain fixed information about the specified call.


LONG WINAPI lineGetCallInfo(
  HCALL hCall,
  LPLINECALLINFO lpCallInfo 
);

hCall

Handle to the call to be queried. The call state of hCall can be any state.

lpCallInfo

Pointer to a variably sized data structure of type LINECALLINFO. Upon successful completion of the request, this structure is filled with call-related information. Prior to calling lineGetCallInfo, the application should set the dwTotalSize member of this structure to indicate the amount of memory available to TAPI for returning information.

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

Value Description

LINEERR_INVALCALLHANDLE

The handle to the call is invalid.

LINEERR_RESOURCEUNAVAIL

The resources are unavailable.

LINEERR_INVALPOINTER

The pointer is invalid.

LINEERR_STRUCTURETOOSMALL

The structure is too small.

LINEERR_NOMEM

Not enough memory is available.

LINEERR_UNINITIALIZED

A parameter is uninitialized.

LINEERR_OPERATIONFAILED

The operation failed.

LINEERR_OPERATIONUNAVAIL

The operation is unavailable.

A separate LINECALLINFO structure exists for every incoming or outgoing call. The structure contains primarily fixed information about the call. An application would typically be interested in checking this information when it receives its handle for a call by the LINE_CALLSTATE message, or each time it receives notification by a LINE_CALLINFO message that parts of the call information structure have changed. These messages supply the handle for the call as a parameter.
