Я могу получить такую структуру:

typedef struct _SYSTEM_THREADS 
{
    ULONGLONG KernelTime;
    ULONGLONG UserTime;
    FILETIME  CreateTime;
    ULONG            WaitTime;
    PVOID            StartAddress;
    CLIENT_ID ClientId;
    LONG        Priority;
    LONG        BasePriority;
    ULONG            ContextSwitchCount;
    LONG            State;
    KWAIT_REASON    WaitReason;
} SYSTEM_THREADS;

и такую:

typedef struct _BASIC_THREAD_INFORMATION 
{
        BOOL ExitStatus;
        PVOID Teb;
        CLIENT_ID ClientID;
        DWORD AffinityMask;
        DWORD BasePriority;
        DWORD Priority;
} BASIC_THREAD_INFORMATION;

а как получить такую?

typedef struct tagTHREADINFO {
    W32THREAD;
