I can't get Posix.installHandler to do what I expect it to do. Attached is a sample
program.
If my reading of the documentation is correct, this should prompt with ">0" for a reply
repeatedly until the user interrupts, after which it replaces the current continuation
with
the supplied handler, thus printing out "Interrupted!", and continuing to prompt with
"1>".
And so on. Following is a sample trace (Sparc/Solaris as always). Note (1) just
before
^C an extra input line seems to get inserted. (2) Somehow the supplied handler doesn't
keep going, instead we return to the old continuation, for no reason I can see.
What is going on?
0>^C
You typed
0>Interrupted!1>
You typed
0>^Casdf
You typed asdf
0>Interrupted!1>
You typed
TestInterrupt.hs
