ICorDebugManagedCallback2::FunctionRemapOpportunity Method

  • Artikkeli

Notifies the debugger that code execution has reached a sequence point in an older version of an edited function.

Syntax

HRESULT FunctionRemapOpportunity (
    [in] ICorDebugAppDomain   *pAppDomain,
    [in] ICorDebugThread      *pThread,
    [in] ICorDebugFunction    *pOldFunction,
    [in] ICorDebugFunction    *pNewFunction,
    [in] ULONG32              oldILOffset
);

Parameters

pAppDomain [in] A pointer to an ICorDebugAppDomain object that represents the application domain containing the edited function.

pThread [in] A pointer to an ICorDebugThread object that represents the thread on which the remap breakpoint was encountered.

pOldFunction [in] A pointer to an ICorDebugFunction object that represents the version of the function that is currently running on the thread.

pNewFunction [in] A pointer to an ICorDebugFunction object that represents the latest version of the function.

oldILOffset [in] The common intermediate language (CIL) offset of the instruction pointer in the old version of the function.

Remarks

This callback gives the debugger an opportunity to remap the instruction pointer to its proper place in the new version of the specified function by calling the ICorDebugILFrame2::RemapFunction method. If the debugger does not call RemapFunction before calling the ICorDebugController::Continue method, the runtime will continue to execute the old code and will fire another FunctionRemapOpportunity callback at the next sequence point.

This callback will be invoked for every frame that is executing an older version of the given function until the debugger returns S_OK.
