PCI_EXPRESS_DEVICE_STATUS_REGISTER union (miniport.h)
The PCI_EXPRESS_DEVICE_STATUS_REGISTER union describes a PCI Express (PCIe) device status register of a PCIe capability structure.
Syntax
typedef union _PCI_EXPRESS_DEVICE_STATUS_REGISTER {
struct {
USHORT CorrectableErrorDetected : 1;
USHORT NonFatalErrorDetected : 1;
USHORT FatalErrorDetected : 1;
USHORT UnsupportedRequestDetected : 1;
USHORT AuxPowerDetected : 1;
USHORT TransactionsPending : 1;
USHORT Rsvd : 10;

USHORT AsUSHORT;
} PCI_EXPRESS_DEVICE_STATUS_REGISTER, *PPCI_EXPRESS_DEVICE_STATUS_REGISTER;
Members
DUMMYSTRUCTNAME
The DUMMYSTRUCTNAME structure.
DUMMYSTRUCTNAME.CorrectableErrorDetected
A single bit that indicates that a correctable error has been detected.
DUMMYSTRUCTNAME.NonFatalErrorDetected
A single bit that indicates that a non-fatal uncorrectable error has been detected.
DUMMYSTRUCTNAME.FatalErrorDetected
A single bit that indicates that a non-fatal uncorrectable error has been detected.
DUMMYSTRUCTNAME.UnsupportedRequestDetected
A single bit that indicates that an unsupported request has been detected.
DUMMYSTRUCTNAME.AuxPowerDetected
A single bit that indicates that AUX power has been detected.
DUMMYSTRUCTNAME.TransactionsPending
A single bit that indicates that the device has issued non-posted requests that have not been completed. The device clears this bit when all outstanding non-posted requests have completed or have been terminated by the completion timeout mechanism.
DUMMYSTRUCTNAME.Rsvd
Reserved.
AsUSHORT
A USHORT representation of the contents of the PCI_EXPRESS_DEVICE_STATUS_REGISTER structure.
Remarks
The PCI_EXPRESS_DEVICE_STATUS_REGISTER structure is available in Windows Server 2008 and later versions of Windows.
A PCI_EXPRESS_DEVICE_STATUS_REGISTER structure is contained in the PCI_EXPRESS_CAPABILITY structure.
