IOCTL_HAL_RELEASE_SYSINTR (Compact 2013)
10/16/2014
This I/O control message releases a previously-requested SYSINTR. Send this message with OEMIoControl.
Syntax
BOOL OEMIoControl(
DWORD dwIoControlCode, // use IOCTL_HAL_RELEASE_SYSINTR
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_RELEASE_SYSINTR for this operation.
- lpInBuffer
[in] Pointer to a DWORD containing a SYSINTR value obtained with the IOCTL_HAL_REQUEST_SYSINTR I/O control.
- nInBufferSize
[in] Set to sizeof(DWORD).
- lpOutBuffer
[out] Set to NULL.
- nOutBufferSize
[out] Set to zero.
- lpBytesReturned
[out] Set to NULL.
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.
The SPI parameters are specific to your platform and can be defined in header files. You can define additional device specific SPI parameters if required.
