分享怎样使自己的程序从开始运行到结束都尽可能的独占cpu啊？！
我现在需要在win2k上做一个小程序，要求是实时的作一些处理。所以我希望我的程序能尽可能的独占cpu而不被系统服务或者其他程序打断。各位高人能给我一些指点吗？谢谢！！

加在InitInstance的AfxEnableControlContainer()后面
BOOL CPriorityTestApp::InitInstance()
{
AfxEnableControlContainer();
SetPriorityClass(GetCurrentProcess(),REALTIME_PRIORITY_CLASS);
......
}
再看进程管理器里面的优先级显示实时的了
BOOL CPriorityTestApp::InitInstance()
{
AfxEnableControlContainer();
SetPriorityClass(GetCurrentProcess(),REALTIME_PRIORITY_CLASS);
......
}

我的程序中没有用到多线程，setPriorityClass能用吗？setPriorityClass中的进程句柄我写什么呢？我的小程序是一个gialog，setPriorityClass应该加在那里呢？

用这个函数
BOOL SetPriorityClass(
HANDLE hProcess, // handle to process
DWORD dwPriorityClass // priority class
);
把进程的Priority Class设成REALTIME_PRIORITY_CLASS
BOOL SetPriorityClass(
HANDLE hProcess, // handle to process
DWORD dwPriorityClass // priority class
);
把进程的Priority Class设成REALTIME_PRIORITY_CLASS

BOOL SetThreadPriority(
HANDLE hThread,
int nPriority
);
Priority Meaning
THREAD_PRIORITY_ABOVE_NORMAL Priority 1 point above the priority class.
THREAD_PRIORITY_BELOW_NORMAL Priority 1 point below the priority class.
THREAD_PRIORITY_HIGHEST Priority 2 points above the priority class.
THREAD_PRIORITY_IDLE Base priority of 1 for IDLE_PRIORITY_CLASS, BELOW_NORMAL_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS, ABOVE_NORMAL_PRIORITY_CLASS, or HIGH_PRIORITY_CLASS processes, and a base priority of 16 for REALTIME_PRIORITY_CLASS processes.
THREAD_PRIORITY_LOWEST Priority 2 points below the priority class.
THREAD_PRIORITY_NORMAL Normal priority for the priority class.
THREAD_PRIORITY_TIME_CRITICAL Base priority of 15 for IDLE_PRIORITY_CLASS, BELOW_NORMAL_PRIORITY_CLASS, NORMAL_PRIORITY_CLASS, ABOVE_NORMAL_PRIORITY_CLASS, or HIGH_PRIORITY_CLASS processes, and a base priority of 31 for REALTIME_PRIORITY_CLASS processes

提高优先级到实时,
怎么做的?
兄台有具件的API函数吗?

怎么设置啊，我现在就是手工在任务管理器中设置，但是我想把它做进我的程序里，程序运行后自动将自己的优先器设置为实时？不知道该怎么设置。另外设置为实时后，win2k的系统服务，或者鼠标、键盘等中断就不会对我的程序产生干扰了吗？？谢谢

提高优先级到实时，但不推荐这么首。
