C/C ++ on Liunx platform Article 4: thread control

Thread advantages (process comparison ):
1. Low overhead
2. Since the same process, each thread can easily access Shared data.
Typical thread applications: asynchronous processing mechanism; processing blocking IO;
The thread function is defined in <pthread. h>
Synchronization Mechanism of shared data by threads:
1. Explicit mutex lock mutex_t
...
To avoid the overhead of frequently creating and destroying threads, you can use the thread pool to reuse threads. For more information, see boost threadpool.
