Hello. I've been searching for a "buffer" class. I mean, a class like std::string with a .data() method that returns a mutable char* instead of a const char*. So I can do something like: std::string buffer; buffer.reserve(SIZE); int n = recv(fd, buffer.data(), SIZE, 0); I know I probably can do that with a cast anyways, but I don't think it's pretty nor "defined behaviour", right? Another thing sometime I need, is some string processing *without* copying. Something like a readonly substring view. What I think of is basically some struct like: struct slice { const char* ptr; size_t len; } which has all the other (at least no-mutable) operation of a string. Something like doing a std::string::substr() but without the copying. Are there any support for this stuff on boost? Do you know any other libraries which have this?

std::vector<char> does that.

Could you use STL algorithms and const iterators? ****************************************************************************** "This message and any attachments are solely for the intended recipient and may contain confidential and privileged information.
