Re: lposix library for Lua 5.1

["Mike Panetta" <panetta.mike@...>]

I added an execvp, which looks like execvp(prog, ...) so its easier to wrap in a lua function such as:

function myexec(file, ...)
         pid = assert(ox.fork())
        if (pid == 0) then -- Child
                ox.execvp(file, arg)
                -- We never get here
        else
                ox.wait(pid)
        end
        return pid
end

I added waitpid which acts just like waitpid in c, and allows you to
specify the type of wait you want to do in the second argument like:
cpid, retval, signo = ox.waitpid(pid, ox.WNOHANG)

This allows you to get more information, such as if the process was killed by a signal etc.

and I added nanosleep which allows you to sleep in smaller increments then a second IE:
ox.nanosleep(.005)

Would this be of interest to anyone?  My error handling of waitpid needs some cleanup I think though.

Thanks! I was looking for glos just the other day.

I am very interested in lposix and I would like it to be a standard
available package in all major linux/bsd distros.

Are all the t2 patches included too?
http://www.t2-project.org/packages/lua-posix.html

I'm intrested in adding crypt(3) (to generate passwords), chroot and a
wrapper to getopt. Where in the file can I add those? Are the funcs in
any particular order?

Would it be an idea to split them in several files, to be scaleable?

How can we help Luiz to get those in to next "official" release of
lposix?

Obrigado!
