A cross-platform library written in Swift 5 for multithreading based on POSIX threads. It has a similar API to Apple’s GCD and in most cases works much faster.

It consists of the following:

• PLock - wrapper for POSIX mutex, analog to NSLock
• PCondition - wrapper for POSIX condition, analog to NSCondition
• PThread - wrapper for POSIX thread, analog to Thread
• PThreadPool - thread pool implementation
• PDispatchQueue - FIFO queue for serially or concurrently executing tasks, analog to DispatchQueue
• PDispatchGroup - group of tasks for aggregation and synchronization, analog to DispatchGroup
• PDispatchSemaphore - semaphore implementation, analog to DispatchSemaphore
• PDispatchWorkItem - block wrapper, analog to DispatchWorkItem
