Quick Info

CMC_return_code cmc_logoff (

Parameters

session

[in] Opaque session handle that represents a MAPI session object indicating a session with a message service. If the session handle is invalid, the cmc_logoff function returns cmc_e_invalid_session_id. After cmc_logoff returns, the session handle is invalid.

ui_id

[in] Handle of a dialog box for cmc_logoff to present to help resolve processing questions.

logoff_flags

[in] Bitmask of flags. The following flags can be set:

CMC_ERROR_UI_ALLOWED

Displays a dialog box on encountering recoverable errors. If this flag is not set, cmc_logoff does not display a dialog box and returns an error value instead.

CMC_LOGOFF_UI_ALLOWED

Indicates cmc_logoff can display a dialog box for other purposes than displaying error messages while logging the user off from the session.

logoff_extensions

[in, out] Pointer to an array of CMC_extensionWY87UR structures containing function extensions. On input, this array contains MAPI extensions to the standard cmc_logoff function. A value of NULL for the logoff_extensions parameter indicates that the client application has no extensions for cmc_logoff and is expecting no extensions.

On output, cmc_logoff writes to the array new information about the logoff operation. It writes NULL if it generates no output extensions.
