Buffering Data Between Threads

A buffer

A lock

A suspend/resume mechanism

Release the lock when you are finished with the resource

线程同步

pthread_join function

Mutex variable functions

Condition variable functions

pthread_once function

Reader/writer exclusion

Threadsafe data structures

Semaphores

线程管理

Thread attributes

The pthread_once mechanism

Scheduling

Mutex scheduling attributes

线程调度

总结

IO、CPU、MEM

atomic、voliate、sleep(0)
