;NOTES:
;
;Now that Be and BeOS are dead, it doesn't really matter.
;This stuff is kept here only for history.. so if yours 'date'
;shows something like "Mon Aug 7 2541 10:23", you may read on
;and marvel at what those ancient crazy humans did.
;
;BeOS port is no longer supported and eternally is in alpha stage
;(though it works sometimes) mostly because of weird BeOS kernel bugs.
;
;Be kernel developers did not want to share any information on syscalls,
;so I had to figure out these constants and system call convention
;manually by disassembling libroot.so (of course BIEW helped a lot).
;As BeOS source code is closed, do not even think of blaming me
;when these teeny inoffensive digits will destroy your hard disk data,
;my BeOS hanged dozens times when I was playing with them.
;
;***
;Yes, syscall with invalid stack kills BeOS, shame on it!
;Likely being the first who tried to play with direct kernel calls
;on BeOS, I had immediatelly run into nasty system crashes.
;
;Be has registered this bug before R5.0, but was not fixed in R5.0
;details are at http://bebugs.be.com/devbugs/detail.php3?oid=2324160
;
;Also there was a discussion on this bug in BeDevTalk mailing list
;during Feb-Mar 2000, it may be of your interest: look for the topics
;"assembly & BeOS", "system calls", "System call stress testing"
;in the BeDevTalk archives at http://www.escribe.com/software/bedevtalk/
;***
;
;Personally I think that at least half of entries here are correct ;)
;
;In BeOS most calls are done through int 0x25, but some
;go through int 0x26 (or syscall/sysenter instructions).
;Quite common is practice of implementing several library calls
;through one kernel call.
;
;Here are listed only int 0x25 calls (and only for R4.5.2)
;
;R5.0 has 0xC7 syscalls
;(according to libroot-obj.tgz, src/kernel/kit/obj.i586.dyn/scalls.o)
;
;BeOS kernel hackers, do you hear me?!
