CVertexBuffer::VBChunk * CVertexBufferManager::Allocate	(	size_t	vertexSize,
		size_t	numVertices,
		GLenum	usage,
		GLenum	target,
		void *	backingStore = `NULL`
	)

Try to allocate a vertex buffer of the given size and type.

Parameters

vertexSize	size of each vertex in the buffer
numVertices	number of vertices in the buffer
usage	GL_STATIC_DRAW, GL_DYNAMIC_DRAW, GL_STREAM_DRAW
target	typically GL_ARRAY_BUFFER or GL_ELEMENT_ARRAY_BUFFER
backingStore	if usage is STATIC, this is NULL; else for DYNAMIC/STREAM, this must be a copy of the vertex data that remains valid for the lifetime of the VBChunk
