Detailed Description

LBuffer is basically a malloc'd buffer with an associated mutex locking access.

LBuffer is basically a malloc'd buffer with an associated mutex lock that can be checked before/locked during reads/writes. It has an "width/height"

Constructor & Destructor Documentation

LBuffer::LBuffer (  int  W, int  H, int  sz )  [inline]

Initializes a lockable buffer, of size W*H*sz (just like a malloc). Parameters: W  Width H  Height sz  Size per element

LBuffer::~LBuffer (   )  [inline]

Deletes the buffer object, and frees its associated memory.

Member Function Documentation

size_t LBuffer::elmentsz (   )  [inline]

Return the number of bytes of each element.

size_t LBuffer::height (   )  [inline]

Return the "height" of the buffer.

void LBuffer::lock (   )  [inline]

Lock the buffer. Any subsequent attempts to lock it while it is already locked will block.

void* LBuffer::ptr (   )  [inline]

Return a pointer to the associated memory.

size_t LBuffer::size (   )  [inline]

Return the size of the buffer (W*H*elementsz).

void LBuffer::unlock (   )  [inline]

Unlock the buffer.

size_t LBuffer::width (   )  [inline]

Return the "width" of the buffer.
