ACE的同步typde类型和宏定义

典型的锁哨宏用法

ACE_GUARD_RETURN (ACE_SYNCH_MUTEX, ace_mon, this->mutex_, -1);

ACE_SYNCH_MUTEX定义在下面的文件中

 

Synch_T.h

同步对象宏定义,

主要提供typedef统一多线程同步定义

 

class ACE_Export ACE_MT_SYNCH

{

public:

  typedef ACE_Thread_Mutex MUTEX;      //线程互斥锁

  typedef ACE_Null_Mutex NULL_MUTEX;         //空互斥锁

  typedef ACE_Process_Mutex PROCESS_MUTEX; // 进程互斥锁

  typedef ACE_Recursive_Thread_Mutex RECURSIVE_MUTEX; // 线程递归互斥锁

  typedef ACE_RW_Thread_Mutex RW_MUTEX; //线程读写锁

  typedef ACE_Condition_Thread_Mutex CONDITION;//线程条件互斥锁

  typedef ACE_Condition_Recursive_Thread_Mutex RECURSIVE_CONDITION; //线程条件互斥递归锁

  typedef ACE_Thread_Semaphore SEMAPHORE; // 线程信号量

  typedef ACE_Null_Semaphore NULL_SEMAPHORE; //空信号量

};
