## Detailed Description

### template<class T, class TbufferKeeper = iRenderBuffer*>
class csRenderBufferLock< T, TbufferKeeper >

Helper class for convenient locking/unlocking of an iRenderBuffer.

The buffer is locked upon construction of the csRenderBufferLock<> object and unlocked on destruction.

The contents can be accessed either directly, array-style or iterator-style in a typed way.

Remarks:
  The TbufferKeeper template argument can be used to have the lock store the buffer in a csRef<iRenderBuffer> (instead a iRenderBuffer*) in case there is a risk that the buffer gets destroyed while thelock exists.

## Constructor & Destructor Documentation

template<class T, class TbufferKeeper = iRenderBuffer*>

csRenderBufferLock< T, TbufferKeeper >::csRenderBufferLock | ( | iRenderBuffer * | buf,
|  | csRenderBufferLockType | lock = `CS_BUF_LOCK_NORMAL` |
| ) |  |  | `[inline]`

Construct the helper.

Locks the buffer.

Definition at line 116 of file rbuflock.h.

template<class T, class TbufferKeeper = iRenderBuffer*>

csRenderBufferLock< T, TbufferKeeper >::~csRenderBufferLock | ( |  | ) | `[inline]`

Destruct the helper.

Unlocks the buffer.
