Detailed Description

Event object for signalling other threads.

Constructor & Destructor Documentation

Event()

Event::Event ( bool  auto_reset = true )

inline

Event constructor.

By default, it will automatically be reset when it's raised.

Parameters

auto_reset

Once this event has been raised, should it automatically be reset?

~Event()

Event::~Event ( )

inline

Destructor.

Member Function Documentation

GetID()

pthread_cond_t* Event::GetID ( )

inline

Get the Event object.

Query()

bool Event::Query ( )

inline

Query the status of this event.

Returns

True if the event is raised, false if not.

Reset()

void Event::Reset ( )

inline

Reset the event status to un-raised.

Wait() [1/3]

bool Event::Wait ( )

inline

Wait until this event is raised.

It is likely this will block this thread (and will never timeout).

See also

Wake

Wait() [2/3]

bool Event::Wait ( const timespec &  timeout )

inline

Wait for a specified amount of time until this event is raised or timeout occurs.

See also

Wake

Wait() [3/3]

bool Event::Wait ( uint64_t  timeout )

inline

Wait for a specified number of milliseconds until this event is raised or timeout occurs.

See also

Wake

WaitNs()

bool Event::WaitNs ( uint64_t  timeout )

inline

Wait for a specified number of nanoseconds until this event is raised or timeout occurs.

See also

Wake

WaitUs()

bool Event::WaitUs ( uint64_t  timeout )

inline

Wait for a specified number of microseconds until this event is raised or timeout occurs.

See also

Wake

Wake()

void Event::Wake ( )

inline

Raise the event.

Any threads waiting on this event will be woken up.
