Hi all,
When using pthread mutexes a number of types are available (man pthread_mutexattr_settype). The normal and recursive types are exposed via boost as boost::mutex and boost::recursive_mutex. I'd like to use PTHREAD_MUTEX_ERRORCHECK mutexes but don't see such a mutex type within boost or C++ std namespaces. I'm wondering why this C feature is not exposed to C++ users. Are there plans to do so? Has it been omitted because this POSIX feature is not portable to other platforms?
No there are no plans. I understand that could be useful for POSIX platforms, but you should have a portable solution for other platforms.
For experimentation purposes I've duplicated then modified the code from boost/thread/recursive_mutex.hpp and boost/thread/pthread/recursive_mutex.hpp to create errorcheck_mutex.hpp on my Fedora 24 system and it gives me the error checking functionality I'm after. Is this a reasonable approach to plug the gap in Boost or is there a reason not to do so?
Good initiative. I believe that we could start by an implementation for POSIX. We will need the code, tests and updated documentation. It will be even best if you fork the github repository and propose a PR. Best, Vicente
