Members

AddrPC

An ADDRESS64 structure that specifies the program counter.

x86:  The program counter is EIP.

Intel Itanium:  The program counter is StIIP.

x64:  The program counter is RIP.

AddrReturn

An ADDRESS64 structure that specifies the return address.

AddrFrame

An ADDRESS64 structure that specifies the frame pointer.

x86:  The frame pointer is EBP.

Intel Itanium:  There is no frame pointer, but AddrBStore is used.

x64:  The frame pointer is RBP or RDI. This value is not always used.

AddrStack

An ADDRESS64 structure that specifies the stack pointer.

x86:  The stack pointer is ESP.

Intel Itanium:  The stack pointer is SP.

x64:  The stack pointer is RSP.

AddrBStore

Intel Itanium:  An ADDRESS64 structure that specifies the backing store (RsBSP).

FuncTableEntry

On x86 computers, this member is an FPO_DATA structure. If there is no function table entry, this member is NULL.

Params[4]

The possible arguments to the function.

Far

This member is TRUE if this is a WOW far call.

Virtual

This member is TRUE if this is a virtual frame.

Reserved[3]

This member is used internally by the StackWalkEx function.

KdHelp

A KDHELP64 structure that specifies helper data for walking kernel callback frames.

StackFrameSize

Set to sizeof(STACKFRAME_EX).

InlineFrameContext

Specifies the type of the inline frame context.

INLINE_FRAME_CONTEXT_INIT (0)

INLINE_FRAME_CONTEXT_IGNORE (0xffffffff)
