Constructor & Destructor Documentation

MutexRef() [1/2]

SDL::MutexRef::MutexRef ( MutexParam  resource )

inlinenoexcept

Parameters

resource

a MutexRaw or Mutex.

This does not takes ownership!

MutexRef() [2/2]

SDL::MutexRef::MutexRef ( MutexRaw  resource )

inlinenoexcept

Parameters

resource

a MutexRaw or Mutex.

This does not takes ownership!

Member Function Documentation

Mutex() [1/2]

SDL::Mutex::Mutex ( )

inline

All newly-created mutexes begin in the unlocked state.

Calls to Mutex.Lock() will not return while the mutex is locked by another thread. See Mutex.TryLock() to attempt to lock without blocking.

SDL mutexes are reentrant.

Postcondition

the initialized and unlocked mutex or nullptr on failure; call GetError() for more information.

Since

This function is available since SDL 3.2.0.

See also

Mutex.Destroy

Mutex.Lock

Mutex.TryLock

Mutex.Unlock

Mutex() [2/2]

constexpr SDL::Mutex::Mutex ( const MutexRaw  resource )

inlineexplicitconstexprnoexcept

Parameters

resource

a MutexRaw to be wrapped.

This assumes the ownership, call release() if you need to take back.
