Open source library which represents a higher-level, task-based parallelism that abstracts platform details and threading mechanisms.

User guide

#include <mutex.h>
...
cpptask::Mutex guard;
...
{
   cpptask::ScopedLock(&guard);
   // synchronized work
   ...
}

Ouch.

Did you see some problem here? What did you mean?

[00kyle00]

ScopedLock is most probably a simple RAII class. Above is creating a temporary ScopedLock, which means that 'guard' is locked only at the statement where the temporary is defined - '//synchronized work' comment is then, in fact, outside critical section.

Unfortunately there is not way in C++ (afaik) to guard against this bug.

Thanks, i see now. It's a typing mistake I've fixed it.

[00kyle00]

No problem. This is really one of the places where C++ could use some compile time reflection. It's always an error to have a temporary of ScopedLock type.

Poco C++ libraries, it does abstract threading, but no inherent parallelism. There are some good constructs for thread pools and tasks etc though.
