Does anybody have any experiance using exec() style commands from within
ada?
I have looked in : Ada as a second Language
The Lovelace tutorial
Ada95 Third Edition.
I have(as yet) been unable to find what I am looking for, does Ada have a
method/package available to interface with the shell? Or is it just that I
have missed something relevant in one of the above books and should just
import the C pragma (something I am trying to avoid).
What I am wanting to do is something a little "perl-esque",
exec(program, argument);
any thoughts?
Thanks for all of the help, Having used this list in the past I know that
I am likely to get a helpful response (the kernel module does just about work).
many thanks,
Mark

If you are using gnat have a look at spawn() and
non_blocking_spawn() in gnat.os_lib.

Yes.

Ada is a language used on many different OSes, and sometimes on bare
hardware, so an "exec()" does not always exist. Therefore you are
unlikely to find it in a general Ada book. Most compiler vendors,
however, supply such a thing with their compiler if at all possible,
so look in your compiler docs.

Don't see this in the documentation. Can you provide
a five or six line program example?

There is quite a large comment for Spawn in the spec file, & the
others refer to it .. normal for GNAT, the info in gnat_rm is just a
hint ..

The spec sources is the documentation.

HmmmmMMMMmmmmm. Someone could do a great favor to
the GNAT users by creating an HTML file of these obscure
resources, or a link from the GNAT user's manual to them. It
is quite annoying to browse through source files in search of
useful features or discover them by surprise.

There is a link in the GNAT Reference Manual. All GNAT units are
described here, the details being in the sources.
