fastcgi C++ dev. kit - few questions

Hi,

I am fairly new to Fast CGI and I am able to write some test
applications with C++ using echo-cpp.cpp as the guideline with apache
1.3.33 under Linux.

I could not search the archives, so I apologise if these issues were
discussed already:

1)  When I use cin.read(bug, sz) or cout.write(buf, sz) methods to
read POST input, or send
    any output, should the developer handle EINTR errors? Glancing at
the sources,
    it seems EINTR errors are not handled?

    i.e

    // fill up my buf with output

    cout.write(buf, sz);

    if (cout.bad())
    {
      // whoops handle errno == EINTR to
      // retry the write() above???
    }

    Currently I don't handle EINTR


2) Is it possible to install a custom signal handler, say SIGUSR2, and send
    it to the mgr process which can dispatch it to all child fcgi processes? Any
    examples on how to do it?

    I could install a handler per child before entering the main
FCGX_Accept_r() loop
    but that would mean sending this signal to each child (the pids
being recorded
    elsewhere...).

    My aim here to force all fastcgi processes to re-read a custom config. file
    without restarting apache.


Thanks,
Ravi
