DacpThreadpoolData Structure

Defines a transport buffer for runtime thread pool 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 DacpThreadpoolData : ZeroInit<DacpThreadpoolData>
{
    LONG cpuUtilization;    
    int NumIdleWorkerThreads;
    int NumWorkingWorkerThreads;
    int NumRetiredWorkerThreads;
    LONG MinLimitTotalWorkerThreads;
    LONG MaxLimitTotalWorkerThreads;

    CLRDATA_ADDRESS FirstUnmanagedWorkRequest;

    CLRDATA_ADDRESS HillClimbingLog;
    int HillClimbingLogFirstIndex;
    int HillClimbingLogSize;

    DWORD NumTimers;

    LONG   NumCPThreads;
    LONG   NumFreeCPThreads;
    LONG   MaxFreeCPThreads; 
    LONG   NumRetiredCPThreads;
    LONG   MaxLimitTotalCPThreads;
    LONG   CurrentLimitTotalCPThreads;
    LONG   MinLimitTotalCPThreads;

    CLRDATA_ADDRESS AsyncTimerCallbackCompletionFPtr;
    
    HRESULT Request(ISOSDacInterface *sos)
    {
        return sos->GetThreadpoolData(this);
    }
};
