NAME

     setfib - set the default FIB (routing table) for the calling process.

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     int
     setfib(int fib);

DESCRIPTION

     The setfib() system call sets the associated fib for all sockets opened
     subsequent to the call, to be that of the argument fib.  The fib argument
     may be between 0 and the current system maximum which may be retrieved by
     the net.fibs sysctl.  The default fib of the process will be applied to
     all protocol families that support multiple fibs, and ignored by those
     that do not.  The default fib for a process may be overidden for a socket
     with the use of the SO_SETFIB socket option.

RETURN VALUES

     The setfib() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS

     The setfib() system call will fail and no action will be taken and return
     EINVAL if the fib argument is greater than the current system maximum.

SEE ALSO

     setsockopt(2), setfib(8)

STANDARDS

     The setfib() system call is a FreeBSD extension however similar
     extensions have been added to many other UNIX style kernels.

HISTORY

     The setfib() function appeared in FreeBSD 8.0.
