EVENT_EXTENDED_ITEM_STACK_KEY32 structure (evntcons.h)

  • Article

Defines an extended item stack key on a 32-bit computer.

Syntax

typedef struct _EVENT_EXTENDED_ITEM_STACK_KEY32 {
  ULONG64 MatchId;
  ULONG   StackKey;
  ULONG   Padding;
} EVENT_EXTENDED_ITEM_STACK_KEY32, *PEVENT_EXTENDED_ITEM_STACK_KEY32;

Members

MatchId

A unique identifier that you use to match the kernel-mode calls to the user-mode calls; the kernel-mode calls and user-mode calls are captured in separate events if the environment prevents both from being captured in the same event. If the kernel-mode and user-mode calls were captured in the same event, the value is zero.

Typically, on 32-bit computers, you can always capture both the kernel-mode and user-mode calls in the same event. However, if you use the frame pointer optimization compiler option, the stack may not be captured, captured incorrectly, or truncated.

StackKey

The key.

Padding

The key padding.
