Hi Matevz,
All of xrootd avoids signals like the plague . The only exceptions is
server-side async I/O where it's required for portability. Then again, of
late, everyone turns that capability off. Anyway, signals aren't really
needed any more and just produce a lot of obtuse difficult to maintain code.
So, I don't see any way you can do this using signals but Lukasz may have a
way of doing this otherwise, However why are you using sync reads anyway? If
this is a problem you should be using async reads.

Subject: XrdCl interrupting sync read
Hi,
I tried to figure out how sigs are masked and handled in xrootd -- but they
don't seem to be used at all (or they are wrapped very well :) ) -- so maybe
the
whole thing below is a nono.
Is it safe to signal a thread doing a synchronous XrdClFile::Read() to make
it
come back with the equivalent of EINTR? What signal should I use for that?
The thread is owned by me ... so I can install signal handlers if it's
needed.
Cheers,
Matevz
