FixedBuffer3cc
A buffer class that holds a known capacity of fixed sized objects defined during creation. producer/consumer buffer for fixed size objects.
Usage
#include <thread.h>
Inherits Buffer.
Public Methods
FixedBuffer (size_t capacity, size_t objsize)
Create a buffer of known capacity for objects of a specified size. FixedBuffer (const FixedBuffer &fb)
Create a copy of an existing fixed size buffer and duplicate it's contents. virtual ~FixedBuffer ()
Destroy the fixed buffer and free the memory used to store objects. FixedBuffer & operator= (const FixedBuffer &fb)
bool isValid (void)
Protected Methods
int onPeek (void *buf)
Return the first object in the buffer. int onWait (void *buf)
Wait for and return a fixed object in the buffer. int onPost (void *buf)
Post an object of the appropriate size into the buffer.

-
pointer to data to copy into the buffer.
Implements Buffer.
int FixedBuffer::onWait (void * buf) [protected, virtual]
Wait for and return a fixed object in the buffer.
Returns: predefined size of this buffers objects.
Parameters:
- buf
-
pointer to hold object returned from the buffer.
Implements Buffer.
