Exposes the properties of a stack frame.


IDiaStackFrame : IUnknown  

Methods in Vtable Order

The following are methods supported by this interface:

Method Description
IDiaStackFrame::get_allocatesBasePointer Retrieves a flag indicating that the base pointer is allocated for code in this address range. This method is deprecated.
IDiaStackFrame::get_base Retrieves the address base of the frame.
IDiaStackFrame::get_cplusplusExceptionHandling Retrieves a flag indicating that C++ exception handling is in effect.
IDiaStackFrame::get_functionStart Retrieves a flag indicating that the block contains the entry point of a function.
IDiaStackFrame::get_lengthLocals Retrieves the number of bytes of local variables pushed on the stack.
IDiaStackFrame::get_lengthParams Retrieves the number of bytes of parameters pushed on the stack.
IDiaStackFrame::get_lengthProlog Retrieves the number of bytes of prologue code in the block
IDiaStackFrame::get_lengthSavedRegisters Retrieves the number of bytes of saved registers pushed on the stack.
IDiaStackFrame::get_localsBase Retrieves the address base of the locals.
IDiaStackFrame::get_maxStack Retrieves the maximum number of bytes pushed on the stack in the frame.
IDiaStackFrame::get_rawLVarInstanceValue Retrieves the value of the specified local variable as raw bytes.
IDiaStackFrame::get_registerValue Retrieves the value of a specified register.
IDiaStackFrame::get_returnAddress Retrieves the return address of the frame.
IDiaStackFrame::get_size Retrieves the size of the frame in bytes.
IDiaStackFrame::get_systemExceptionHandling Retrieves a flag indicating that system exception handling is in effect.
IDiaStackFrame::get_type Retrieves the frame type.


A stack frame is an abstraction of a function call during its execution.

Notes for Callers

Obtain this interface by calling the IDiaEnumStackFrames::Next method. See the IDiaEnumStackFrames interface for an example on obtaining the IDiaStackFrame interface.


This example displays various attributes of a stack frame.
