hehehe... some voodoo? dark magic?
are you talking about the fact that both the RedHat RPM Guide and RPM
API say its rpmReadSignature( FD_t fd, Header * header, sigType
sig_type) but the actual call in the file you mentioned adds a 4th
parameter (I checked it on the src.rpm, and its like it) ?

Thank you for your pointers.

It seems like mostly I will just write some wrapper around rpm's
commands whenever I need to do something the easy way with 'C'.
