// Class : ConditionVarDirect
|
|
// Description : A condition variable, usually used to communicate
|
|
// information about changing state to a thread that is
|
|
// waiting for something to happen. A condition
|
|
// variable can be used to "wake up" a thread when some
|
|
// arbitrary condition has changed.
|
|
//
|
|
// A condition variable is associated with a single
|
|
// mutex, and several condition variables may share the
|
|
// same mutex.
