Re: Passing C struct values automatically to Lua

[zweifel <zweifel@...>]

In my case it is mostly anonymous. I call the script from C by lua_pcall.

I checked the arg variable and it is nil. I am reading things about debug.getinfo now, but I found nothing about anonymous calls...

This is true, but the 'function' (or rather, chunk) which is executed
when your script runs is anonymous.

However, the arg table is always available if your code runs as a
script. The caveat is that this applies to the Lua executable itself;
it may not make sense in an embedded environment (but then you could
set a helpful global)

For plain Lua, arg[-1] is the path of the Lua executable, arg[0] is
the script (path included, maybe) and arg[1]...arg[#arg] are the
command-line arguments.
