Detailed Description

Keyed-mutex guard used while sharing a D3D texture.

Constructor & Destructor Documentation

texture_lock_helper() [1/2]

platf::dxgi::texture_lock_helper::texture_lock_helper ( texture_lock_helper && other )

inline

Move a keyed-mutex lock helper while preserving lock ownership.

Parameters

other

Helper whose acquired keyed mutex is transferred.

texture_lock_helper() [2/2]

platf::dxgi::texture_lock_helper::texture_lock_helper ( IDXGIKeyedMutex * mutex )

inline

Acquire a D3D keyed mutex for scoped texture access.

Parameters

mutex

Keyed mutex to acquire for texture access.

Member Function Documentation

lock()

bool platf::dxgi::texture_lock_helper::lock ( )

inline

Acquire the underlying lock or keyed mutex.

Returns

True when the keyed mutex is acquired.

operator=()

texture_lock_helper & platf::dxgi::texture_lock_helper::operator= ( texture_lock_helper && other )

inline

Assign state from another instance while preserving ownership semantics.

Parameters

other

Source object whose state is copied or moved into this object.

Returns

Reference or value produced by the operator.
