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.
