Functions

DAApprovalSessionCreate: Creates a new approval session.
DAApprovalSessionGetTypeID: Returns the type identifier of all DAApprovalSession instances.
DAApprovalSessionScheduleWithRunLoop: Schedules the approval session on a run loop.
DAApprovalSessionUnscheduleFromRunLoop: Unschedules the approval session from a run loop.
DASessionCreate: Creates a new session.
DASessionGetTypeID: Returns the type identifier of all DASession instances.
DASessionScheduleWithRunLoop: Schedules the session on a run loop.
DASessionUnscheduleFromRunLoop: Unschedules the session from a run loop.

DAApprovalSessionCreate

Creates a new approval session.

extern DAApprovalSessionRef DAApprovalSessionCreate(
    CFAllocatorRef allocator );

Return Value

A reference to a new DAApprovalSession.

Discussion

The caller of this function receives a reference to the returned object. The caller also implicitly retains the object and is responsible for releasing it.

DAApprovalSessionGetTypeID

Returns the type identifier of all DAApprovalSession instances.

extern CFTypeID DAApprovalSessionGetTypeID(
    void );

DAApprovalSessionScheduleWithRunLoop

Schedules the approval session on a run loop.

extern void DAApprovalSessionScheduleWithRunLoop(
    DAApprovalSessionRef session,
    CFRunLoopRef runLoop,
    CFStringRef runLoopMode );

Parameters

session: The approval session which is being scheduled.
runLoop: The run loop on which the approval session should be scheduled.
runLoopMode: The run loop mode in which the approval session should be scheduled.

DAApprovalSessionUnscheduleFromRunLoop

Unschedules the approval session from a run loop.

extern void DAApprovalSessionUnscheduleFromRunLoop(
    DAApprovalSessionRef session,
    CFRunLoopRef runLoop,
    CFStringRef runLoopMode );

Parameters

session: The approval session which is being unscheduled.
runLoop: The run loop on which the approval session is scheduled.
runLoopMode: The run loop mode in which the approval session is scheduled.

DASessionCreate

Creates a new session.

extern DASessionRef DASessionCreate(
    CFAllocatorRef allocator );

Return Value

A reference to a new DASession.

Discussion

The caller of this function receives a reference to the returned object. The caller also implicitly retains the object and is responsible for releasing it.

DASessionGetTypeID

Returns the type identifier of all DASession instances.

extern CFTypeID DASessionGetTypeID(
    void );

DASessionScheduleWithRunLoop

Schedules the session on a run loop.

extern void DASessionScheduleWithRunLoop(
    DASessionRef session,
    CFRunLoopRef runLoop,
    CFStringRef runLoopMode );

Parameters

session: The session which is being scheduled.
runLoop: The run loop on which the session should be scheduled.
runLoopMode: The run loop mode in which the session should be scheduled.

DASessionUnscheduleFromRunLoop

Unschedules the session from a run loop.

extern void DASessionUnscheduleFromRunLoop(
    DASessionRef session,
    CFRunLoopRef runLoop,
    CFStringRef runLoopMode );

Parameters

session: The session which is being unscheduled.
runLoop: The run loop on which the session is scheduled.
runLoopMode: The run loop mode in which the session is scheduled.
