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

NAME
     ggeettssoocckknnaammee - get socket name

SYNOPSIS
     ##iinncclluuddee <>

     int
     ggeettssoocckknnaammee(int socket, struct sockaddr *restrict address,
         socklent *restrict addresslen);

DESCRIPTION
     GGeettssoocckknnaammee() returns the current address for the specified socket.  The
     addresslen parameter should be initialized to indicate the amount of
     space pointed to by address.  On return it contains the actual size of
     the name returned (in bytes).

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

EERRRROORRSS
     The ggeettssoocckknnaammee() system call will succeed unless:

     [EBADF]            The argument socket is not a valid file descriptor.

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

     [EINVAL]           socket has been shut down.

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

     [ENOTSOCK]         The argument socket is not a socket (e.g., a plain
                        file).

     [EOPNOTSUPP]       ggeettssoocckknnaammee() is not supported for the protocol in use
                        by socket.

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

HISTORY     The ggeettssoocckknnaammee() call appeared in 4.2BSD.
