lineShutdown

The lineShutdown function shuts down the application's usage of the line abstraction of the API.

LONG WINAPI lineShutdown(
  HLINEAPP hLineApp  
);

Parameters

hLineApp

The application's usage handle for the line API.

Return Values

Returns zero if the request succeeds or a negative error number if an error occurs. Possible return values are:

LINEERR_INVALAPPHANDLE, LINEERR_RESOURCEUNAVAIL, LINEERR_NOMEM, LINEERR_UNINITIALIZED.

Remarks

If this function is called when the application has lines open or calls active, the call handles are deleted and TAPI automatically performs the equivalent of a lineClose on each open line. However, it is recommended that applications explicitly close all open lines before invoking lineShutdown. If shutdown is performed while asynchronous requests are outstanding, those requests are canceled.

Requirements

  Windows NT/2000: Requires Windows NT 4.0 SP3 or later.
  Windows 95/98: Requires Windows 95 or later.
  Version: Requires TAPI 1.3 or later.
  Header: Declared in Tapi.h.
  Library: Use Tapi32.lib.
