The lineGetCallInfo function enables an application to obtain fixed information about the specified call.
LONG lineGetCallInfo(
HCALL hCall,
LPLINECALLINFO lpCallInfo
);
Returns zero if the request succeeds or a negative error number if an error occurs. Possible return values are:
LINEERR_INVALCALLHANDLE, LINEERR_RESOURCEUNAVAIL, LINEERR_INVALPOINTER, LINEERR_STRUCTURETOOSMALL, LINEERR_NOMEM, LINEERR_UNINITIALIZED, LINEERR_OPERATIONFAILED, LINEERR_OPERATIONUNAVAIL.
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.
