如何查看在命名管道中排队的数据量？

netstat -n -p | findstr "pipe"

#include<windows.h>
#include<stdio.h>

int main()
{
    HANDLE hPipe;
    DWORD dwState, dwCurInstances, dwMaxCollectionCount;

    hPipe = CreateNamedPipe(TEXT("\\\\.\\pipe\\mypipe"),
        PIPE_ACCESS_DUPLEX,
        PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE | PIPE_WAIT,
        PIPE_UNLIMITED_INSTANCES,
        1024,
        1024,
        0,
        NULL);

    if (hPipe == INVALID_HANDLE_VALUE)
    {
        printf("CreateNamedPipe failed, GLE=%d.\n", GetLastError());
        return -1;
    }

    if (!GetNamedPipeInfo(hPipe, &dwState, &dwCurInstances, &dwMaxCollectionCount))
    {
        printf("GetNamedPipeInfo failed, GLE=%d.\n", GetLastError());
        return -1;
    }

    printf("State: %d\n", dwState);
    printf("Current instances: %d\n", dwCurInstances);
    printf("Maximum collection count: %d\n", dwMaxCollectionCount);

    CloseHandle(hPipe);

    return 0;
}
