Subject:	RE: Problem: SIGCONT handler is not called (Cygwin or Bash problem ?)

All,

i tried this also under ash and tcsh: same result. The SIGCONT handler is
never called and the program blocks. Therefore i do think the problem is not
shell related.
On Unix systems (as far as i remember it) it is normally the kernel that
sets/clears the user area of the program stack, including the address
pointer of the signal handler and the return address where to resume normal
execution.
How does this happen on Cygwin ? Is this handled by the Cygwin1.dll ?  If
so, does this mean it is broken for SIGCONT handling ?

PS: Could anyone reproduce the problem using the test programs i sent ? I'm
rather in the dark
on what is happening and why.

best regards,
Rudi

.......
My problem is that the SIGCONT handler is never triggered (as it seems to
me). I could reduce the problem into the following code snippets.
.....
Questions:
1) is there a problem with the SIGCONT handling in CYGWIN ? Why is it never
called or is SIGCONT not delivered ?
2) what is the signal delivery scheme in Cygwin for SIGCONT i.e. what is
called first after issueing a shell - fg command ?
3) or do i miss something in my code here that would be specific for Cygwin
(i tested it on various other Unix platforms with success) ?
