C callable library to do HTTP get/put form data

John Kittel — Mon, 08 Dec 2003 18:20:06 GMT

Are there C callable libraries / routines avaiable for HP-UX 11i 64-bit to do HTTP get/put form data?

I don't really understand too well what I'm asking here, this is coming from one of my "advanced users" ( who knows more than I do).

Thanks,
John

I would point him towards GNU's cgicc library.

http://hpux.connect.org.uk/hppd/hpux/Gnu/cgicc-3.0.2/

However, I think I would try to push him towards Perl and the CGI module. The development times will be 10x faster and the performance will be all but indistinguishable from Native C or C++.

Thank you Clay.

Are there other options?

Of the options you mention, I think I will have to go with cgicc library. We have to somehow invoke these functions from within an existing application ( uses a language called Gembase DML ). We know how to call C routines. I wouldn't know how to attempt to call perl from within the application ( unless perhaps it would be completely transparent, i.e. exactly the same, to the app whether it was linking to a C library or a perl program). I think our needs will be fairly modest and so maybe the development time won't be prohibitive. And, the "advanced user" I mentioned is not actually going to be doing the work, he is only telling me what we need, and yet another person here is going to do the programming, and I think he'd be more comfortable with C than perl. ( He's at least done some C programming.)

... darn, once again I replied before I finished thinking....

I didn't think/notice that cgicc is a c++ library ( duh!). I don't know if our application programming language ( Gembase DML) can link to that, or only to C, or even if there is a difference.

... and now I see that curl-7.9.8 is available on the hp porting and archive center.

I will check that avenue out.

Calling apps like curl and wget (via
system() or whatnot) might work for
simple HTTP requests, but to do anything
robust you'd probably be better off
using a C API as you originally suggested.
The curl authors have a really nice
summary of HTTP libraries at:
