fairly basic question on command options

[Mark]

can anyone confirm whether or not C++ places any restrictions on the length
of
command option strings passed into main upon startup. The standard ( section
3.6) does'nt seem to mention any, but I thought I'd better confirm.

My guess is that , if there are any, it might be implementation or OS/shell
defined.

If you got the Standard document, you got all the help you need. We'd be
using the same document to "confirm".

That's correct. Any limits of that sort are OS-driven, most likely, and
since your implementation has to live in the confines of your OS, the same
limits can be interpreted as implementation-defined.

As an example of an implementation, using the gcc compiler suite,
configure checks up on this.
