I am having problems getting my SYSUNINIT function called when I do a
kldunload.
I have reduced my source file to containing nothing more than a sysinit and
sysunit function,
both of which only print out a diagnostic. I believe the setdef files look
OK. I have traced
through the loader symbol look up function, and the sysinit_set name is
there, but the
sysuninit_set name is not. I do get the diagnostic printed from my sysinit
function.
Since there is nothing to the files, I am including the source file try.c,
the Makefile,
the generated setdef files, and the symbol printouts. The total of
everything is less than
1 1/2 pages.
Thank you.
