- Summary
Creates a semaphore.<BR>
- Parameters
InitialCount |
denotes the starting value the semaphore. If you set it to
zero, the first acquire() blocks. Otherwise InitialCount acquire()s are
immedeatly successfull.
|
- Return
0 if the semaphore could not be created, otherwise a handle to the sem.
-

- ~Semaphore();

- Summary
acquire()decreases the count. It will block if it tries to
decrease below zero.
- Return
False if the system-call failed.

- Description
tryToAcquire()tries to decreases the count. It will
return with False if it would decrease the count below zero.
(When acquire() would block.) If it could successfully
decrease the count, it will return True.

- Summary
The underlying oslSemaphore has no reference count.
- Description
Since the underlying oslSemaphore is not a reference counted object, copy
constructed Semaphore may work on an already destructed oslSemaphore object.

- Summary
The underlying oslSemaphore has no reference count.
- Description
When destructed, the Semaphore object destroys the undelying oslSemaphore,
which might cause severe problems in case it's a temporary object.
