问题描述

根据MSDN，用户模式调度程序(UMS)API需要64位OS.
http://msdn.microsoft.com/zh-cn/library/dd627165.aspx

但是我在winbase.h中找不到这样的要求，该要求包括在Windows 7的Windows SDK中和.NET Framework 3.5 SP1:"RC" (请参见下文).
另一个宏(例如 _WIN64)?

According to MSDN, User Mode Scheduler (UMS) API requires 64-bit OS.
http://msdn.microsoft.com/en-us/library/dd627165.aspx

But I cannot find such requirement in winbase.h included in "Windows SDK for Windows 7 and .NET Framework 3.5 SP1: RC" (see below).
Another macro (e.g. _WIN64) is needed?

//
// UMS begin
//

#if (_WIN32_WINNT >= 0x0601) && !defined(MIDL_PASS)

#define UMS_VERSION RTL_UMS_VERSION

typedef void *PUMS_CONTEXT;

typedef void *PUMS_COMPLETION_LIST;

typedef enum _RTL_UMS_THREAD_INFO_CLASS UMS_THREAD_INFO_CLASS, *PUMS_THREAD_INFO_CLASS;

typedef enum _RTL_UMS_SCHEDULER_REASON UMS_SCHEDULER_REASON;

typedef PRTL_UMS_SCHEDULER_ENTRY_POINT PUMS_SCHEDULER_ENTRY_POINT;

typedef struct _UMS_SCHEDULER_STARTUP_INFO {

    //
    // UMS Version the application was built to. Should be set to UMS_VERSION
    //
    ULONG UmsVersion;

    //
    // Completion List to associate the new User Scheduler to.
    //
    PUMS_COMPLETION_LIST CompletionList;

    //
    // A pointer to the application-defined function that represents the starting
    // address of the Sheduler.
    //
    PUMS_SCHEDULER_ENTRY_POINT SchedulerProc;

    //
    // pointer to a variable to be passed to the scheduler uppon first activation.
    //
    PVOID SchedulerParam;

} UMS_SCHEDULER_STARTUP_INFO, *PUMS_SCHEDULER_STARTUP_INFO;
