pthread mutex question

pthread mutex question

[sankar]

Hi,
I am looking for an idea as to how to implement timed mutex using pthread
libraries on linux.
Basically I want to associate a timeout value with the wait function i,e
pthread_mutex_lock() which returns once the timeout expires instaed of
waiting for ever.
Pls help

thx..

Its C++, but you could have a look at the boost::thread::timed_mutex 
(www.boost.org) implementation, which makes use of pthread_cond_timedwait.

You're probably looking at the abstract model. Download the source and 
look at timed_mutex::do_timedlock, in mutex.cpp.
