void acedia::util::Semaphore::acquire

(

boost::int32_t

n = 1

)

Acquire n resources.

This method blocks if there are not enough resources available.

Definition at line 271 of file acedia_util.cpp.

bool acedia::util::Semaphore::tryAcquire	(	boost::int32_t	n,
		boost::uint16_t	msTimeout
	)

Try to acquire n resrouces.

This method blocks if there are not enough resources available but waits at most msTimeout milliseconds.

Returns:

true if n resources are acquired; otherwise false

bool acedia::util::Semaphore::tryAcquire

(

boost::int32_t

n = 1

)

Try to acquire n resrouces.

This method does not block and returns always immediately.

Returns:

true if n resources are acquired; otherwise false
