InterProcessLock()

juce::InterProcessLock::InterProcessLock ( const String &  name )

enter()

bool juce::InterProcessLock::enter

(

int

timeOutMillisecs = -1

how many milliseconds to wait if the lock is already held by another process - a value of 0 will return immediately, negative values will wait forever

Returns

true if the lock could be gained within the timeout period, or false if the timeout expired.
