Detailed Description

We have an internal implementation of the mutex to avoid leaking the pthread library to the outside.

The class holds a mutex and a condition which we use to wait in various circumstances such as when we pop items from a currently empty fifo.

Member Data Documentation

f_condition

pthread_mutex_t cppthread::detail::mutex_impl::f_condition = pthread_cond_t()

We often have to signal that a thread is done in regard to something or other. That will wake up another thread which can then take over the next step of the work.

The condition is used for that purpose as we can wait on it with the attached mutex.

f_mutex

pthread_mutex_t cppthread::detail::mutex_impl::f_mutex = pthread_mutex_t()

This is the actual system mutex. It is useful to protect areas of code that only one thread is allowed to access at a time.

The mutex also supports a condition that it can wait on and signal. This is useful to signal a new state such as the end of FIFO as any thread waiting on that FIFO now needs to wake up a give up (no more messages will be sent to the FIFO).
