DacpThreadData Structure

Defines a transport buffer for runtime thread information.

Note

This API was originally designed for internal use in the runtime. Although it is now supported for 3rd party use, we recommend working with ICorDebug and ICorProfiler APIs when possible.

Syntax

struct DacpThreadData : ZeroInit<DacpThreadData>
{
    DWORD corThreadId;
    DWORD osThreadId;
    int state;
    ULONG preemptiveGCDisabled;
    CLRDATA_ADDRESS allocContextPtr;
    CLRDATA_ADDRESS allocContextLimit;
    CLRDATA_ADDRESS context;
    CLRDATA_ADDRESS domain;
    CLRDATA_ADDRESS pFrame;
    DWORD lockCount;
    CLRDATA_ADDRESS firstNestedException; // Pass this pointer to DacpNestedExceptionInfo
    CLRDATA_ADDRESS teb;
    CLRDATA_ADDRESS fiberData;
    CLRDATA_ADDRESS lastThrownObjectHandle;
    CLRDATA_ADDRESS nextThread;

    HRESULT Request(ISOSDacInterface *sos, CLRDATA_ADDRESS addr)
    {
        return sos->GetThreadData(addr, this);
    }
};

Members

Member Description
corThreadId The managed thread identifier.
osThreadId The operating system thread identifier.
state The thread state flags.
preemptiveGCDisabled A value that indicates whether preemptive garbage collection is disabled for the thread.
allocContextPtr The current allocation context pointer for the thread.
allocContextLimit The allocation context limit for the thread.
context The address of the thread context.
domain The address of the application domain for the thread.
pFrame The address of the current frame.
lockCount The number of locks held by the thread.
firstNestedException The address of the first nested exception. Pass this pointer to DacpNestedExceptionInfo.
teb The address of the thread environment block.
fiberData The address of the fiber data.
lastThrownObjectHandle The handle for the last object thrown on the thread.
