CSSM_ModuleUnload(3)
NAME
  CSSM_ModuleUnload - Deregister event notification callbacks (CDSA)

SYNOPSIS
  # include <cdsa/cssm.h>

       CSSM_RETURN CSSMAPI CSSM_ModuleUnload
       (const CSSM_GUID *ModuleGuid,
       CSSM_API_ModuleEventHandler AppNotifyCallback,
       void* AppNotifyCallbackCtx)

LIBRARY
  Common Security Services Manager library (libcssm.so)

PARAMETERS
  ModuleGuid (input)
	  The GUID of the module selected for unloading.

  AppNotifyCallback (input/optional)
	  The event notification function to be deregistered. The function
	  must have been provided by the caller in CSSM_ModuleLoad().

  AppNotifyCallbackCtx (input/optional)
	  The event notification context that was provided in the
	  corresponding call to CSSM_ModuleLoad().

DESCRIPTION
  The function deregisters event notification callbacks for the caller
  identified by ModuleGuid. The CSSM_ModuleUnload() function is the analog
  call to CSSM_ModuleLoad().  If all callbacks registered with CSSM are
  removed, then CSSM unloads the service module that was loaded by calls to
  CSSM_ModuleLoad().  Calls to CSSM_ModuleUnload() that are not matched with
  a previous call to CSSM_ModuleLoad() result in an error.

  The CSSM uses the three input parameters ModuleGuid, AppNotifyCallback, and
  AppNotifyCallbackCtx to uniquely identify registered callbacks.

  This function should be invoked after all necessary calls to
  CSSM_ModuleDetach() have been performed.

RETURN VALUE
  A CSSM_RETURN value indicating success or specifying a particular error
  condition. The value CSSM_OK indicates success. All other values represent
  an error condition.

ERRORS
  Errors are described in the CDSA technical standard.	See CDSA_intro(3).

       CSSMERR_CSSM_ADDIN_UNLOAD_FAILED
       CSSMERR_CSSM_EMM_UNLOAD_FAILED
       CSSMERR_CSSM_EVENT_NOTIFICATION_CALLBACK_NOT_FOUND
