Constructor taking the size of an object within the buffer.

Destructor.

This frees the memory allocated to the buffer.

Gets the current number of objects in this circular buffer.

Implementation function for CCirBuf::Add(const T*)

Adds a single object to the circular buffer, but only if there is space available.

Implementation function for CCirBuf::Add(const T*,TInt)

Adds multiple objects to the circular buffer, but only if there is space available.

Implementation function for CCirBuf::Remove(T*)

Removes a single object from the circular buffer, but only if there are objects in the buffer.

A binary copy of the object is made to aPtr.

CCirBuf::Remove

Implementation function for CCirBuf::Remove(T*,TInt)

Attempts to remove aCount objects from the circular buffer, but only if there are objects in the buffer.

A binary copy of the objects is made to aPtr.

Gets the maximum capacity of this circular buffer.

The capacity is the maximum number of elements that the buffer can hold.

Use SetLengthL() to change the capacity of the circular buffer.

CCirBufBase::SetLengthL

Empties the buffer.

Sets the maximum capacity of this circular buffer, and resets all of the buffer pointers.

The capacity is the maximum number of elements that the buffer can hold.

The buffer itself is allocated as a result of a call to this function. If the function has previously been called, then any existing buffer is freed and any information in it is lost.

Notes:

1. This function must be called before attempting to add any objects to the buffer.

2. The function can leave if there is insufficient memory available to allocate the buffer.
