Functions | |
DBG_DEFAULT_CHANNEL (UserPowerManager) | |
static VOID | IntHandlePowerEventWorker (_In_ PWIN32_POWEREVENT_PARAMETERS pParameters) |
Handles a power event as a result from an incoming power callout from the kernel power manager. | |
static NTSTATUS | IntValidateWin32PowerParams (_In_ PWIN32_POWEREVENT_PARAMETERS pParameters) |
Validates the power event parameters that come from a power callout from the kernel power manager. | |
static PWIN32POWERCALLOUT | IntGetNextPowerCallout (_In_ PWIN32POWERCALLOUT pPowerCallout) |
Gets the next pending power callout from the global queue list and returns it to the caller. Note that the returned power callout is delisted from the list. | |
static VOID | IntDeployPowerCallout (VOID) |
Deploys all pending power callouts to appropriate power callout workers. | |
static VOID | IntEnlistPowerCallout (_In_ PWIN32POWERCALLOUT pPowerCallout) |
Enlists a newly allocated power callout into the queue list for later processing. | |
NTSTATUS NTAPI | IntInitWin32PowerManagement (_In_ HANDLE hPowerRequestEvent) |
Initializes the power management side of Win32 kernel-mode subsystem component. This enables communication between the power manager of the NT kernel and Win32k. | |
NTSTATUS NTAPI | IntWin32PowerManagementCleanup (VOID) |
Cleanup procedure that frees all the allocated resources by the power manager. It is triggered during Win32k subsystem unloading. | |
NTSTATUS NTAPI | IntHandlePowerEvent (_In_ PWIN32_POWEREVENT_PARAMETERS pWin32PwrEventParams) |
Handles an incoming power event callout from the NT power manager. | |
NTSTATUS NTAPI | IntHandlePowerState (_In_ PWIN32_POWERSTATE_PARAMETERS pWin32PwrStateParams) |
Handles an incoming power state callout from the NT power manager. | |

static |
Gets the next pending power callout from the global queue list and returns it to the caller. Note that the returned power callout is delisted from the list.
[in] | pPowerCallout | A pointer to a power callout entry that was previously returned by the same function. If this parameter is set to NULL the function will return the first callout entry from the list. Otherwise the function will return the next callout entry of the current power callout. |
