IcomLUO.Offline Method

Artigo
04/19/2022

Switches the LU0 session into an off-line state, which in turn causes the underlying SNA session to deactivate.

Syntax

  
void Offline()

Parameters

Return Value

Value	Description
S_OK	The session has been successfully deactivated.
CLU0_E_WAITING	Another thread has issued a Receive call for this comLU0 method, which has not yet returned.
CLU_E_SERVER_FAILURE	The TSS session is no longer valid. The application should release the session handle.
CLU0_E_RECEIVE_IN_PROGRESS	The application has not yet completed receiving the last chain sent by the host. This may be indicated by Receive returning DATA_INCOMPLETE. You should re-issue the IcomLU0.Receive call to collect the remaining data, and then call IcomLU0.Offline again.
CLU0_E_SYSERROR	This method failed due to an internal error.

Exceptions

Remarks

After calling Offline, the client application can later reactivate the session using a call to Online.

Note that Offline releases the SNA server LU. Therefore, it is possible for another application to acquire the LU before your application calls Online again.

You can use Online to recover a session that has returned CLU0_E_SESSION_FAILED.
