win32 线程优先级 - c++编程基础

SetThreadPriority 设置指定线程的优先级
[cpp]
BOOL SetThreadPriority( HANDLE hThread, // handle to the thread
int nPriority // thread priority level);
参数说明
　　hThread 要设置的线程句柄
　　nPriority 优先级别参数可设置为一下参数
　　THREAD_PRIORITY_ABOVE_NORMAL 比一般优先级高一个等级
　　THREAD_PRIORITY_BELOW_NORMAL 比一般低一个等级
　　THREAD_PRIORITY_HIGHEST 比一般高2个等级（最高）
　　THREAD_PRIORITY_IDLE 空闲
　　THREAD_PRIORITY_LOWEST 比一般低2个等级（最低）
　　THREAD_PRIORITY_NORMAL 一般等级
　　THREAD_PRIORITY_TIME_CRITICAL 实时
