PCI_EXPRESS_AER_CAPABILITIES union (wdm.h)
The PCI_EXPRESS_AER_CAPABILITIES structure describes a PCI Express (PCIe) advanced error capabilities and control register of a PCIe advanced error reporting capability structure.
Syntax
typedef union _PCI_EXPRESS_AER_CAPABILITIES {
struct {
ULONG FirstErrorPointer :5;
ULONG ECRCGenerationCapable :1;
ULONG ECRCGenerationEnable :1;
ULONG ECRCCheckCapable :1;
ULONG ECRCCheckEnable :1;
ULONG Reserved :23;
};
ULONG AsULONG;
} PCI_EXPRESS_AER_CAPABILITIES, *PPCI_EXPRESS_AER_CAPABILITIES;
