IOCTL_HAL_GET_POOL_PARAMETERS (Compact 2013)

10/16/2014

This I/O control message modifies page pool parameters at run-time. Send this message with OEMIoControl.

Syntax

BOOL OEMIoControl(
    DWORD dwIoControlCode,    // use IOCTL_HAL_GET_POOL_PARAMETERS
    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_GET_POOL_PARAMETERS for this operation.
  • nInBufferSize
    [in] Size of the NKPagePoolParameters structure.
  • lpOutBuffer
    [in] Set to NULL.
  • nOutBufferSize
    [in] Set to zero.
  • lpBytesReturned
    [in] Set to NULL.

Return Values

Returns TRUE if successful; otherwise, returns FALSE.

Remarks

OEMs implement OEMIoControl, and the kernel calls OEMIoControl with this I/O control value to invoke the OEM's implementation of that I/O control.

Alternatively, rather than implementing this I/O control code, you can control the paging pool setting by using the FIXUPVAR values.
