Hi,

I have a function, that must return a "unsigned long".
If I return a c++ - "true" the compiler doesn't warn.
I know that it is ok in c++, but do I have any chance
to find automaticly all this places in my (big) code, to avoid errors?

Try turning up the warnings e.g. -Wall -W or something similar.

-Wall is turned on

Also a lint tool like splint will likely catch those as well.

Thank you, I try this

Markus
