Provides the parent dispatch service for a power button event.
|
|
|
|
This service registers a function (DispatchFunction) which will be called when an MMI is
|
|
generated because the power button was pressed or released, as specified by RegisterContext.
|
|
On return, DispatchHandle contains a unique handle which may be used later to unregister the
|
|
function using UnRegister().
|
|
The DispatchFunction will be called with Context set to the same value as was passed into
|
|
this function in RegisterContext and with CommBuffer and CommBufferSize set to NULL.
|
|
|
|
@param[in] This Pointer to the EFI_MM_POWER_BUTTON_DISPATCH_PROTOCOL instance.
|
|
@param[in] DispatchFunction Function to register for handler when power button is pressed or released.
|
|
@param[in] RegisterContext Pointer to the dispatch function's context. The caller fills in this context
|
|
before calling the Register() function to indicate to the Register() function
|
|
the power button MMI phase for which the dispatch function should be invoked.
|
|
@param[out] DispatchHandle Handle generated by the dispatcher to track the function instance.
|
|
|
|
@retval EFI_SUCCESS The dispatch function has been successfully
|
|
registered and the MMI source has been enabled.
|
|
@retval EFI_DEVICE_ERROR The driver was unable to enable the MMI source.
|
|
@retval EFI_INVALID_PARAMETER RegisterContext is invalid. The power button input value
|
|
is not within valid range.
|
|
@retval EFI_OUT_OF_RESOURCES There is not enough memory (system or MM) to manage this child.
