Member Function Documentation
| virtual bool TC::MT::Semaphore::Wait | ( | ) | [pure virtual] |
if semaphore value is > 0 then decrement it and carry on.
If it's already 0 then block until > 0.
| virtual bool TC::MT::Semaphore::TryWait | ( | ) | [pure virtual] |
if semaphore value is > 0 then decrement it and return 1 (true).
If it's already 0 then return 0 (false).
| virtual bool TC::MT::Semaphore::TryWait | ( | uint32 | millisecs | ) | [pure virtual] |
if semaphore value is > 0 then decrement it and return 1 (true).
If it's already 0 then block for maximum specified time until > 0
| virtual bool TC::MT::Semaphore::Post | ( | ) | [pure virtual] |
if any threads are blocked in wait(), wake one of them up.
Otherwise increment the value of the semaphore.
