This IOCTL is no longer supported as of Windows CE .NET 4.1. Instead, use the IOCTL_HAL_REQUEST_SYSINTR IOCTL.
The OEMIoControl function calls this IOCTL.
Parameters
- dwIoControlCode
[in] Set to IOCTL_HAL_TRANSLATE_IRQ.
- lpInBuf
[in] IRQ to translate into a SYSINTR.
- nInBufSize
[in] Size of lpInBuf.
- lpOutBuf
[out] SYSINTR translated from an IRQ.
- nOutBufSize
[out] Size of lpOutBuf.
- lpBytesReturned
[in] If not NULL, set to size of DWORD.
Return Values
TRUE indicates success. FALSE indicates failure.
Remarks
A bus driver reads its SYSINTR and IRQ values from the registry, if necessary. For a built-in device, set up the mapping in the OEMInit function and place the SYSINTR in the associated registry entry for the device. Bus drivers, such as the PCI bus driver, use IOCTL_HAL_REQUEST_SYSINTR to allocate SYSINTRs and subsequently populate the registry for the device it is loading a driver for.
