4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Provides the parent dispatch service for a power button event.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This service registers a function (DispatchFunction) which will be called when an SMI is
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync generated because the power button was pressed or released, as specified by RegisterContext.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync On return, DispatchHandle contains a unique handle which may be used later to unregister the
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync function using UnRegister().
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The DispatchFunction will be called with Context set to the same value as was passed into
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync this function in RegisterContext and with CommBuffer and CommBufferSize set to NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] This Pointer to the EFI_SMM_POWER_BUTTON_DISPATCH2_PROTOCOL instance.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] DispatchFunction Function to register for handler when power button is pressed or released.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param[in] RegisterContext Pointer to the dispatch function's context. The caller fills in this context
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync before calling the Register() function to indicate to the Register() function
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the power button SMI phase for which the dispatch function should be invoked.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This service removes the handler associated with DispatchHandle so that it will no longer be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync called when the standby button is pressed or released.
