Hello hackers...
I got strange problem when trying to implement something like exceptions
with setjmp()/longjmp() functions.
[...]
int ret;
jmpbuf buf;
[...]
ret = setjmp(buf);
KASSERT(ret != 1, ("I never return 1 with longjmp()."));
[...]
longjmp(buf, value_diffrent_than_1);
[...]
And setjmp() returns only 0 or 1 (when longjmp() is called), but never
returns value that I've put in longjmp() call.
There could be some other problems in using setjmp()/longjmp()
in kernel? I'm paying attention on memory leaks and locks that are
done before longjmp().
