Hi William! Thank you for the email. It has clarified the things for me. :) I still have one question though.
Do I understand right that I need also to cast types with these types from inttypes.h? So use it not only in the defenitions. - sprintf(buf, "%lu", (long unsigned int)maxsize); + sprintf(buf, "%" PRIu64, (uint64_t)maxsize); Thanks, Simon ----- Original Message ----- > From: "William Brown" <[email protected]> > To: "389-devel" <[email protected]> > Sent: Thursday, March 8, 2018 12:42:03 AM > Subject: Use of int types in the code base, > > Hi there, > > http://www.port389.org/docs/389ds/development/coding-style.html#types > > In a few reviews I still see this sometimes. > > It's pretty important that we keep moving our quality standard higher, > and having known type sizes is important to this.
