STACKFRAME structure (dbghelp.h)

Represents a stack frame.

Syntax

typedef struct _tagSTACKFRAME {
 ADDRESS AddrPC;
 ADDRESS AddrReturn;
 ADDRESS AddrFrame;
 ADDRESS AddrStack;
 PVOID FuncTableEntry;
 DWORD Params[4];
 BOOL Far;
 BOOL Virtual;
 DWORD Reserved[3];
 KDHELP KdHelp;
 ADDRESS AddrBStore;
} STACKFRAME, *LPSTACKFRAME;

Members

AddrPC

An ADDRESS 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 ADDRESS structure that specifies the return address.

AddrFrame

An ADDRESS 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 ADDRESS 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.

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 StackWalk function.

KdHelp

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

AddrBStore

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

Remarks

This structure supersedes the STACKFRAME structure. For more information, see Updated Platform Support. STACKFRAME is defined as follows in Dbghelp.h.

#if !defined(_IMAGEHLP_SOURCE_) && defined(_IMAGEHLP64)
#define STACKFRAME STACKFRAME64
#define LPSTACKFRAME LPSTACKFRAME64
#else
typedef struct _tagSTACKFRAME {
 ADDRESS AddrPC; // program counter
 ADDRESS AddrReturn; // return address
 ADDRESS AddrFrame; // frame pointer
 ADDRESS AddrStack; // stack pointer
 PVOID FuncTableEntry; // pointer to pdata/fpo or NULL
 DWORD Params[4]; // possible arguments to the function
 BOOL Far; // WOW far call
 BOOL Virtual; // is this a virtual frame?
 DWORD Reserved[3];
 KDHELP KdHelp;
 ADDRESS AddrBStore; // backing store pointer
} STACKFRAME, *LPSTACKFRAME;
#endif
