Deregister Application (QNMDRGAP) API

Required Parameter Group:

1	Handle	Input	Binary(4)
2	Error code	I/O	Char(*)

Default Public Authority: *USE

Threadsafe: No

The Deregister Application (QNMDRGAP) API, an SNA/Management Services Transport API, removes the registration of the application name associated with a handle. The QNMDRGAP API only deregisters the application; the application can continue to send requests as long as replies are expected.

Only registered applications can receive requests from remote systems. After an application is deregistered, the remote applications are sent error messages notifying them that the application is not available to receive requests. In addition, it can no longer receive error messages from requests that did not request a reply. Therefore, the application should not send any request-only data.

The QNMDRGAP API is used by applications that do not want to continue receiving requests. The End Application (QNMENDAP) API automatically removes registration before ending the application instance. See the End Application (QNMENDAP) API for more information.
