Hi crydev,

write data from a list/vector to the memory

Is that really what you wanted to write? If yes, then copying data from Vector to other location in memory can be as simple as calling memcpy(dest, vector.Begin(), count*itemsize).

If you actually meant copying from/to file on disk, then Streams are probably the easiest way to go. AFAIK there is currently nothing using memory mapped files in U++. But to use it for storing, it should be just a simple call to mmap (on Linux) followed by memcpy.

Best regards,
Honza
