| DLLEXPORT int QoreCounter::dec | ( | ExceptionSink * | xsink | ) |
decrements the counter and wakes up any threads if the counter reaches 0
a Qore-language exception will be raised here if QoreCounter::destructor() has already been run before calling this function.
| xsink | any Qore-language exception thrown will be added here |
| DLLEXPORT int QoreCounter::inc | ( | ) |
increments the counter
| DLLEXPORT int QoreCounter::waitForZero | ( | ExceptionSink * | xsink, |
| int | timeout_ms = 0 |
||
| ) |
blocks the calling thread until the counter reaches 0
a Qore-language exception will be raised here if QoreCounter::destructor() is run while threads are still blocked
| xsink | any Qore-language exception thrown will be added here |
| timeout_ms | indicates a timeout in milliseconds to wait, 0 means no timeout |
