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 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.

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 StackWalk64 function.

KdHelp

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

AddrBStore

Intel Itanium:  An ADDRESS64 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;
    ADDRESS     AddrReturn;
    ADDRESS     AddrFrame;
    ADDRESS     AddrStack;
    PVOID       FuncTableEntry;
    DWORD       Params[4];
    BOOL        Far;
    BOOL        Virtual; 
    DWORD       Reserved[3];
    KDHELP      KdHelp;
    ADDRESS     AddrBStore; 
} STACKFRAME, *LPSTACKFRAME;
#endif
