GCond* | gobj () |
An opaque data structure to represent a condition.
A Cond is an object that threads can block on, if they find a certain condition to be false. If other threads change the state of this condition they can signal the Cond, such that the waiting thread is woken up.
Glib::Threads::Cond::Cond | ( | ) |
Glib::Threads::Cond::~Cond | ( | ) |
void Glib::Threads::Cond::broadcast | ( | ) |
If threads are waiting for this Cond, all of them are woken up.
It is good practice to hold the same lock as the waiting thread, while calling this method, though not required.

void Glib::Threads::Cond::signal | ( | ) |
If threads are waiting for this Cond, exactly one of them is woken up.
It is good practice to hold the same lock as the waiting thread, while calling this method, though not required.
void Glib::Threads::Cond::wait | ( | Mutex& | mutex | ) |
Waits until this thread is woken up on this Cond.
The mutex is unlocked before falling asleep and locked again before resuming.
mutex | a Mutex that is currently locked. |
bool Glib::Threads::Cond::wait_until | ( | Mutex& | mutex, |
gint64 | end_time | ||
) |
Waits until this thread is woken up on this Cond, but not longer than until the time, that is specified by end_time.
The mutex is unlocked before falling asleep and locked again before resuming.
mutex | a Mutex that is currently locked. |
end_time | a max time to wait. |
