signal handlers

For you it sounds very stupid, but I have almost no experience with gnu
hurd, particularly in programming. I want to port a C Program to Hurd.
My questions are:
Can I use signal() from <signal.h> with all the signals, the same way as
in Linux and BSD? Or are in Hurd different headers and functions for
signal handlers?

Sorry for My bad english and the stupid questions ;D
Is this the right mailing list?

best regards
