Hi,

I get the following warning:

process.cc:192: warning: ANSI C++ prohibits conversion from `(int)' to `(...)'

Here is the relevant part of my source:

  {
    struct sigaction act;

    act.sa_handler = SIG_IGN;
    act.sa_flags   = 0;

    sigemptyset(&act.sa_mask);

    if (sigaction(SIGTTOU, &act, NULL) != 0) PANIC;
    if (sigaction(SIGTTIN, &act, NULL) != 0) PANIC;
    if (sigaction(SIGTSTP, &act, NULL) != 0) PANIC;
  }

The line tha gives the warning is the "act.sa_handler = SIG_IGN" line. I don't
know why I'm getting this warning. The books I have say this is okay (Rago:
UNIX SysV Net. Prog.), the man page says this is okay as well. The sa_handler
field can be either:

a void (*handler)() or SIG_IGN or SIG_DFL

What gives? I'm using  SunOS 5.4 and g++ 2.7.2.

I'd appreciate being CC'ed as well. TIA.

Dave.
