(C++) Execl() is not my friend...

[thedevilsjester]

My program needs to launch a web browser to use an 'online help' functionality, however I have not been able to successfully call a program from within my program.

Well thats not entirely true, I can call any app that I have developed, they all work just fine. However if I try to call any other app, I get an outpouring of X errors. I tried multiple apps with the same results. This is with using execl().

Now with System() I can call any app no problem, except for the obvious pitfall that System() doesnt return until the app it calls terminates.

Anyone know why X is yelling at me for trying these apps? Or even better, does anyone know a better command to achive this?

Here is the X error.

X Error: code 14 major 1 minor 0: BadIDChoice (invalid resource ID chosen for this connection).

I'm going to move this post to the "Coding/Scripting" forum. I think you'll get a better response, there.

Hm... no reply though after moving this post to here. Anyway, I also have encountered the weird Excl() and I change system(). Maybe we should read man more to understand it.
