Having troubles using XkbKeycodeToKeysym

[Mibi88]

Hi,

I found out what was the problem while writing a little test program as 
Enrico Weigelt asked: my test program worked properly. My real program 
wasn't working properly because I was not passing a struct as a pointer 
somewhere, and gcc didn't showed me a warning nor an error message, 
because I didn't noticed that they were not in the header.

Thanks a lot for your help!
