Values for SigBlk and SigIgn are zero in /proc/$$/status

Values for SigBlk and SigIgn are zero in /proc/$$/status

[Ken SATO]

Hello,

When I run the following command, the values for SigBlk and SigIgn are zero.
How can I get the correct value?

$ cat /proc/$$/status

You can't.  We don't have the information readily available without
asking the process itself.  While we have a communication mechanism
in place for stuff like that, it's not used yet for signal info.

It's something we can think about for 3.4, though.

I had a few spare cycles today so I took a stab at it and implemented
it.  I uploaded new developer snapshots to https://cygwin.com/snapshots/,
please give it a try.


Thanks,

Thank you for providing the snapshot.
I was able to get the values of SigBlk and SigIgn.

Below are the results I have tried.
