Detailed Description

Wrapper for Windows semaphore objects.

A semaphore is a counter incremented by signal and decremented by wait. If counter is negative any waiting thread is blocked until counter becomes positive.

Constructor & Destructor Documentation

semaphore()

mlib::semaphore::semaphore	(	int	limit = INT_MAX,
		const std::string &	name = std::string ()
	)

Parameters

limit	maximum limit for counter
name	object's name
