Member Function Documentation

AllocateBuffer()

void OutputBufferManager::AllocateBuffer

(

size_t

size

)

allocate a new output buffer.

Parameters

size	[bytes] to allocate.

notes:

• if a buffer had previously been allocated and is large enough, it is reused (this reduces the number of allocations).
• this class manages the lifetime of the buffer.
