There's a solution, though:
if(fd user requested is in use by me) {
dup2(fd, unused_fd);
close(fd);
switch to using unused_fd myself;
}
I'm not sure how you'd do that under stdio, though, unless you made illicit
use of the file descriptors:
#ifdef SYSV_STDIO
#define fdreopen(fp, fd) ((fp)->__file=(fd))
#endif
My BSD system is sitting on the shelf right now, or I'd check if this was
the right macro there...
