  • Article

1/5/2010

This IOCTL requests a hardware-to-IRQ mapping based on device location.

The OEMIoControl function calls this IOCTL.

Parameters

  • dwIoControlCode
    [in] Set to IOCTL_HAL_REQUEST_IRQ.
  • nInBufSize
    [in] Size of lpInBuf.
  • lpOutBuf
    [out] Interrupt number.
  • nOutBufSize
    [out] Size of lpOutBuf.
  • lpBytesReturned
    [out] If not NULL, set to size of DWORD. If multiple interrupts are mapped to the hardware device, lpBytesReturned is set to the size of DWORD times the number of interrupts.

Return Values

TRUE indicates success. FALSE indicates failure.

Remarks

If multiple interrupts are mapped to the hardware device, lpOutBuf points to the starting interrupt in an array of interrupts, and nOutBufSize contains the size of the array, in bytes.

Requirements

Header pkfuncs.h
Windows Embedded CE Windows CE .NET 4.0 and later
