SETFIB(2)						      BSD System Calls Manual							 SETFIB(2)

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

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <sys/socket.h>

     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 over-
     ridden 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 maxi-
     mum.
