fsal_status_t CEPHFSAL_test_access	(	fsal_op_context_t *	extcontext,
		fsal_accessflags_t	access_type,
		fsal_attrib_list_t *	object_attributes
	)

FSAL_test_access : Tests whether the user identified by the p_context structure can access the object as indicated by the access_type parameter. This function tests access rights using cached attributes given as parameter (no calls to filesystem). Thus, it cannot test FSAL_F_OK flag, and asking such a flag will result in a ERR_FSAL_INVAL error.

Parameters:

p_context	(input): Authentication context for the operation (user,...).
access_type	(input): Indicates the permissions to test. This is an inclusive OR of the permissions to be checked for the user identified by cred. Permissions constants are : FSAL_R_OK : test for read permission FSAL_W_OK : test for write permission FSAL_X_OK : test for exec permission FSAL_F_OK : test for file existence
object_attributes	(mandatory input): The cached attributes for the object to test rights on. The following attributes MUST be filled : owner, group, mode, ACLs.

Returns:

Major error codes :

• ERR_FSAL_NO_ERROR (no error, permission granted)
• ERR_FSAL_ACCESS (object permissions doesn't fit asked access type)
• ERR_FSAL_INVAL (FSAL_test_access is not able to test such a permission)
• ERR_FSAL_FAULT (a NULL pointer was passed as mandatory argument)
• Another error code if an error occured.
