Comment (by taeuber):
Hi Michael,
this is how I would implement it:
{{{
int interactive()
{
int fd, interactive;
fd = open ("/dev/tty", O_RDONLY);
if (fd < 0)
return fd;
interactive = (tcgetpgrp(fd) == getpgid(0));
close (fd);
return interactive;
}
}}}
I have no idea about autoconf tools.
But this doesn't solve the problem. It only tests foreground or background
processing.
Maybe an additional command line option would be the solution of choice?
Lars
