OEMGetInterrupt (Windows Embedded CE 6.0)

This function helps implement the IOCTL_HAL_REQUEST_IRQ IOCTL in the OEMIoControl routine.

The PCI bus enumerator also uses this function to request an IRQ for a PCI device.

Syntax

BOOL OEMGetInterrupt(
  PDEVICE_LOCATION pDevLoc, 
  PDWORD Irq
);

Parameters

  • Irq
    [out] IRQ associated with pDevLoc.

Return Value

TRUE indicates success.

FALSE indicates failure.

Remarks

This is platform-specific information. The logical location of the device is required to determine the IRQ.

Most PCI implementations have the four PCI IRQs rotating for each device number. In addition, it is standard for PCI-to-PCI bridges to have device zero's INTA connect to INTA on the upstream side.

Requirements
