Exposes the properties of a stack frame.

Syntax

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.

Remarks

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.

Example

This example displays various attributes of a stack frame.

void PrintStackFrame(IDiaStackFrame* pFrame)  
{  
    if (pFrame != NULL)  
    {  
        ULONGLONG bottom = 0;  
        ULONGLONG top    = 0;  
  
        if (pFrame->get_base(&bottom) == S_OK &&  
            pFrame->get_registerValue( CV_REG_ESP, &top ) == S_OK )  
        {  
             printf("range = 0x%08I64x - 0x%08I64x\n", bottom, top);  
        }  
  
        ULONGLONG returnAddress = 0;  
        if (pFrame->get_returnAddress(&returnAddress) == S_OK)  
        {  
             printf("return address = 0x%08I64x\n", returnAddress);  
        }  
  
        DWORD lengthFrame     = 0;  
        DWORD lengthLocals    = 0;  
        DWORD lengthParams    = 0;  
        DWORD lengthProlog    = 0;  
        DWORD lengthSavedRegs = 0;  
        if (pFrame->get_size(&lengthFrame) == S_OK &&  
            pFrame->get_lengthLocals(&lengthLocals) == S_OK &&  
            pFrame->get_lengthParams(&lengthParams) == S_OK &&  
            pFrame->get_lengthProlog(&lengthProlog) == S_OK &&  
            pFrame->get_lengthSavedRegisters(&lengthSavedRegs) == S_OK)  
        {  
            printf("stack frame size          = 0x%08lx bytes\n", lengthFrame);  
            printf("length of locals          = 0x%08lx bytes\n", lengthLocals);  
            printf("length of parameters      = 0x%08lx bytes\n", lengthParams);  
            printf("length of prolog          = 0x%08lx bytes\n", lengthProlog);  
            printf("length of saved registers = 0x%08lx bytes\n", lengthSavedRegs);  
        }  
    }  
}
