Can people clarify my understanding here? According to wikipedia Freebsd is only mostly compliant with POSIX, yet BSD/OS is fully- why would this be? >From what I can tell ANSI C is the standard, and POSIX is an implementation(?) of that standard (threads, i/o, etc)? Which version of these standards is Freebsd at- c89, c90, c99, POSIX 1(b,c, etc)? Excuse my ignorance- for reference I am reading the Developers guidebook and the architecture book atm :)
