These functions only make sense if you're working with formatted texts. (you *can* use them for binary data, but that doesn't give any benefit, just slows things down).and even unistd's write() and seek() are wrappers for kernel's pwrite().No. Just look at the code. write()+seek() as different semantics than pwrite(), and they don't even need to be supported by some particular fd.
Wouldn't this work? (no error checking of course XD) off_t lseek(int fd, off_t offset, int whence); ssize_t write(int fd, const void *buf, size_t count);ssize_t pwrite(int fd, const void *buf, size_t count, off_t offset) {
lseek(fd, offset, SEEK_SET);
return write(fd, buf, count);

I tend to consider Javascript as a junk language, but my opinion on it is not well educated. It might be good for what it was designed for.Well, it once was designed for tiny things like alert() on a button click, some trivial input validations, etc. Today, it's totally abused (and nodejs is even worse). If I could travel back in time, I'd shoot the guy who introduced that ugly language.
I found "lua.js" <https://github.com/tdzl2003/lua.js#use-on-html>. (Lua is actually pretty good, but running like that?) -- This email has NOT been checked for viruses by Avast antivirus software. http://0xc9.net Of course, there is _absolutely nothing_ stopping me from saying it _has_. Use common sense and most of your "security" becomes redundant. GPG Key: 0xF4CB50441726610D5AE0
