No, not at all. Or may be I don't see something... Merging changes in why.cpp which are conflicting with the patch I prepared last week - that was nightmare. > Yes provided it's enough. > Assignment of many pointers is often slower than copying memory region. But why one would like to assign many pointers? If to take for given that buffer is a class with unknown internal structure, then it is enough to assign a pointer to it if your code is going to use only buffer's official interface or create a new buffer of suitable structure and copy all data into it, letting original buffer go. There is no need to force your code (engine) to work with any kind of buffer or return a buffer with any user's format. Engine can return its buffers in own format and then it is up to user - work with them as via official interface is or to convert it into something more suitable. -- WBR, SD. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
