This I/O control message enables an interrupt source to wake the system. Send this message with OEMIoControl.

Syntax

BOOL OEMIoControl(
    DWORD dwIoControlCode,    // use IOCTL_HAL_ENABLE_WAKE
    LPVOID lpInBuffer,        // pointer to input buffer
    DWORD nInBufferSize,      // input buffer size
    LPVOID lpOutBuffer,       // pointer to output buffer
    DWORD nOutBufferSize,     // output buffer size
    LPDWORD lpBytesReturned   // number of bytes returned
);

Parameters

  • dwIoControlCode
    [in] Control code for the operation. Use IOCTL_HAL_ENABLE_WAKE for this operation.
  • lpInBuffer
    [in] Set to the dwSysIntr of the driver, which is the source of the interrupt.
  • nInBufferSize
    Ignored.
  • lpOutBuffer
    Ignored.
  • nOutBufferSize
    Ignored.
  • lpBytesReturned
    Ignored.

Return Values

Returns TRUE if successful; otherwise, returns FALSE.

Remarks

To get extended error information, call GetLastError. GetLastError may return other standard error messages as appropriate.

Remarks

This I/O control helps enable the interrupt line associated with the provided SYSINTR value.

Note

If the interrupt line is shared among other devices with different SYSINTR values, the devices may also become wake sources.
