Use the lineGetRegisterStatus function to retrieve the network registration status of the device.


LONG WINAPI lineGetRegisterStatus(
  HLINE hLine,
  LPDWORD lpdwRegisterStatus
);

hLine

The line device handle. The line device handle must have been previously obtained by a call to lineOpen with the proper TAPI device ID specified and a device-specific extension version successfully negotiated with lineNegotiateExtVersion.

lpdwRegisterStatus

The current registration status. See the Registration Status constants for possible values.

Returns zero if the function completes successfully, or a negative error number if an error occurs. The following are possible return values:

  • LINEERR_RESOURCEUNAVAIL
  • LINEERR_INVALLINEHANDLE
  • LINEERR_STRUCTURETOOSMALL
  • LINEERR_INVALPOINTER
  • LINEERR_UNINITIALIZED
  • LINEERR_NOMEM
  • LINEERR_OPERATIONUNAVAIL
  • LINEERR_OPERATIONFAILED

The lineGetRegisterStatus function is synchronous. No LINE_REPLY message is sent, and you can use the contents of the parameter structures immediately after this function call.
