Hmmm ... stderr maybe, something like
FILE* io[3];
int notty = 1;
io[0] = stdin;
io[1] = stdout;
io[2] = stderr;
io[3] = NULL;
for (n=0; io[n]; n++) {
int fd = isatty(fileno(io[n]));
if (tcgetattr(fd, &tio) == 0) {
notty = 0
break;
}
}
could work.
Btw: I've lost your mail
Alternative startpar implementation - live-net-startpar
please resend. Beside any startpar it could be an option
to use a directory based boot scheme as insserv aloready
uses a tsort which can be mapped on `directory' based
sorting scheme. Could work simliar like the process_path()
routine of simpleinit ;)
