As you said, the first lines of queue.scm define some %car,... to
1/ be inlined
2/ use ##sys#slot
Is it mandatory to do this to be included in the disabling-
interrupts file ?
Both of 1/ and 2/ ?
No. Is it not mandatory to ever use a sys namespace routine (there
are a few exceptions) & one should try not to use such routines. Do
not be confused by the use of ##sys#slot, etc. by mailbox. As I said
earlier it is the style of the original author & historical to boot.
If the above is true, what are the real primitives of chicken (that
can thus be used without 'getting out' of the file) ?
I do not understand "... without 'getting out' of the file".
Stay away from the "true" primitives of Chicken. These are inlined C
code. Chicken is primarily a compiler. You can see these things by
looking in the .scm source for Chicken units, like library.scm.
Whenever possible do not stray from R5RS or a SRFI. Your situation is
a little special since you are hacking an existing egg that does
stray (mostly for no good reason except history). You can freely
intermix '(##sys#slot p 1)' & '(cdr p)', they are the same thing. The
compiler will even recognize 'cdr' & inline it.
Again, the use of ##sys# stuff in mailbox is historical & not an
example for preferred style. Except for '##sys#thread-unblock!' &
'##sys#delq' which are unavailable in the global namespace.
'##sys#current-thread', '##sys#structure?', & '##sys#make-structure'
are available in other forms, & ##sys#check-structure can be done
differently.
Thanks, and sorry for those lengthy questions,
mt
No problem. Thanks for making look inside the mailbox code. I spotted
a bug. (Fixed.)
Best Wishes,
Kon
