ICorDebugChain Interface

Represents a segment of a physical or logical call stack.

interface ICorDebugChain : IUnknown {
    HRESULT EnumerateFrames (
        [out] ICorDebugFrameEnum **ppFrames
    );
        
    HRESULT GetActiveFrame (
        [out] ICorDebugFrame     **ppFrame
    );
        
    HRESULT GetCallee (
        [out] ICorDebugChain     **ppChain
    );
        
    HRESULT GetCaller (
        [out] ICorDebugChain     **ppChain
    );
        
    HRESULT GetContext (
        [out] ICorDebugContext   **ppContext
    );
        
    HRESULT GetNext (
        [out] ICorDebugChain     **ppChain
    );
        
    HRESULT GetPrevious (
        [out] ICorDebugChain     **ppChain
    );
        
    HRESULT GetReason (
        [out] CorDebugChainReason *pReason
    );
        
    HRESULT GetRegisterSet (
        [out] ICorDebugRegisterSet **ppRegisters
    );
        
    HRESULT GetStackRange (
        [out] CORDB_ADDRESS      *pStart, 
        [out] CORDB_ADDRESS      *pEnd
    );
        
    HRESULT GetThread (
        [out] ICorDebugThread    **ppThread

Methods

Method	Description
ICorDebugChain::EnumerateFrames Method	Gets an enumerator that contains all the managed stack frames in the chain, starting with the most recent frame.
ICorDebugChain::GetActiveFrame Method	Gets the active (that is, most recent) frame on the chain.
ICorDebugChain::GetCallee Method	Gets the chain that was called by this chain.
ICorDebugChain::GetCaller Method	Gets the chain that called this chain.
ICorDebugChain::GetContext Method	Not implemented.
ICorDebugChain::GetNext Method	Gets the next chain of frames for the thread.
ICorDebugChain::GetPrevious Method	Gets the previous chain of frames for the thread.
ICorDebugChain::GetReason Method	Gets the reason for the genesis of this calling chain.
ICorDebugChain::GetRegisterSet Method	Gets the register set for the active part of this chain.
ICorDebugChain::GetStackRange Method	Gets the address range of the stack segment for this chain.
ICorDebugChain::GetThread Method	Gets the physical thread this call chain is part of.
ICorDebugChain::IsManaged Method	Gets a value that indicates whether this chain is running managed code.

Remarks

The stack frames in a chain occupy contiguous stack space and share the same thread and context. A chain may represent either managed or unmanaged code chains. An empty ICorDebugChain instance represents an unmanaged code chain.
