I'm looking for an existing function similar to memcpy that can be told to copy x bytes and then skip y bytes, repeating until a specified amount has been copied.
Imagine a buffer with data: AABAAB (I've used characters, but the data I'm manipulating is not string data).
When applied to this buffer and told to copy 2 bytes and skip 1 byte, the destination buffer would contain: AAAA.
I haven't found anything looking through STL and Boost, but am hoping there's something in either that I've missed.
Or perhaps there's a clever (and not nasty) way of using more common functions to achieve the same thing.
There doesn't appear to be a direct equivalent of memcpy for doing what I wanted. Boost does seem to often some useful helper functions, but I ended up implementing a simple looping function to do the job as it seemed the most simple & appropriate solution.
