Some questions on the use of MIDI Manager 2.0 en Macintosh Common Lisp 2.0
1) Is it possible to use Lisp-functions at interrupt level in
Macintosh Common Lisp ?
If so, do you have to use the (not yet implemented) traps
_setcurrenta5 and _seta5 from the Pascal Interface
'OSUtils.p' in MCL 2.0 b1 ?
If so, would it be possible to define it before the new MCL
version is released and if so, how ?
How could I use the (following) inline-definitions of the traps
#| Not in ROM - INLINE = #x2E8D #x2A78 #x0904
(deftrap _setcurrenta5 nil
#| Not in ROM - INLINE = #x2F4D #x0004 #x2A5F
(deftrap _seta5 ((newa5 :signed-long))
(from the Pascal Interface "OSUtils.p" in MCL 2.0 b1)
2) Does the MIDI-Manager call 'readhooks' and 'timeprocs' at
If so, would it be possible to use Lisp-functions defined by the
function defpascal as 'readhooks' or 'timeprocs' ?
If not, how could I define Lisp-functions to be 'readhooks' or
'timeprocs' of the MIDI-Manager ?
We would really appreciate if you could answer any of these
questions. At the moment we are writing code using the MIDI-
Manager 2.0 in the Macintosh Common Lisp 2.0
environment.waiting for these questions/problems to be resolved.
