Take the Standard C Library. Create a new namespace, "boost::xtd::" for instance. For every function in the Standard C Library, create an analog in the "boost::xtd::" namespace. The analog function would have the same functional behavior as the StdCLib function, with the notable difference that any errors will generate an exception.
Personally, I find this to be a good idea. Whenever I had to write code like:
int controlling_tty = open(ctermid(0), O_RDWR); if (controlling_tty == -1) perror("open");
int result = tcsetpgrp(controlling_tty, parent_group); if (result == -1) perror("tcsetpgrp");
I really wish there were exception-throwing versions -- since that code is boring and still contains a couple of error-handling problems. However, most of the functions above are acutally from POSIX, not from standard C, so I'm not sure how much wrapped C functions would help me.
Unless I'm mistaken, you're talking something similar to Andrei Alexandrescu's ENFORCE: http://www.cuj.com/documents/s=8250/cujcexp2106alexandr/ As a side-note, I'm implementing SMART_ENFORCE in the smart_assert library. Unfortunately in the latest months I did not have time for it. Hopefully I'll have some time in the next couple of weeks to port it to vc7.1 and post a new version. Best, John
