ignored return values

[andreas moroder]

Hello,

I try to find bug in smaba using splint. One of the most common warnings are 
the "ignored return values". In server.c there are 40 function calls where 
the return value is ignored. Is this ok. What's the sense of return values if 
they are ignored. Ok, I ignore return values of close() too.

Is there a rule which values can be ignored and which should allways be 
checked ?

Thanks

Andreas
