lineShutdown (Windows Embedded CE 6.0)
1/6/2010
This function shuts down the application's usage of the line abstraction of the API.
Syntax
LONG lineShutdown(
HLINEAPP hLineApp
);
Parameters
- hLineApp
[in] Application's usage handle for the line API.
Return Value
Zero indicates success. A negative error number indicates that an error occurred. The following table shows the return values for this function.
Value | Description |
---|---|

The app handle is invalid. |
LINEERR_NOMEM |

LINEERR_RESOURCEUNAVAIL |

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.
