all platforms. The only exceptions (and I will not deal with them anytime soon) are on Windows: - the write functions which require the length to be an int when it's a size_t on all UNIX variants. - all iovec manipulation functions where the iov_len is again an int when it's a size_t on most of the UNIXes. As these only happens on Windows, so I think we're set for now :) This commit was SVN r12215.
