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.

SEE ALSO

     setfib(1), setsockopt(2)

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 7.1.

GETSOCKNAME(2)						      BSD System Calls Manual						    GETSOCKNAME(2)

NAME

     getsockname -- get socket name

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/socket.h>

     int
     getsockname(int s, struct sockaddr * restrict name, socklen_t * restrict namelen);

DESCRIPTION

     The getsockname() system call returns the current name for the specified socket.  The namelen argument should be initialized to indicate the
     amount of space pointed to by name.  On return it contains the actual size of the name returned (in bytes).

RETURN VALUES

     The getsockname() 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 call succeeds unless:

     [EBADF]		The argument s is not a valid descriptor.

     [ECONNRESET]	The connection has been reset by the peer.

     [EINVAL]		The value of the namelen argument is not valid.

     [ENOTSOCK] 	The argument s is a file, not a socket.

     [ENOBUFS]		Insufficient resources were available in the system to perform the operation.

     [EFAULT]		The name argument points to memory not in a valid part of the process address space.

SEE ALSO

     bind(2), getpeername(2), socket(2)

HISTORY

     The getsockname() system call appeared in 4.2BSD.

BUGS

     Names bound to sockets in the UNIX domain are inaccessible; getsockname() returns a zero length name.
