Do you want to do anything with the return value?

[danakj, 2011/09/21 20:58:20]

I don't know, only the GLX one can fail.  In the previous code it just ignored
the fact that it had failed, thus I do the same.  What would you like to happen
?

[danakj, 2011/09/21 21:15:37]

It is back practice to ignore return errors, so if it fails to initialize, I'll
destroy the object and return.  Adding it to the containers list is just likely
to run into more difficult to trace bugs.
