GETSOCKNAME(E)      Linux Programmer's Manual      GETSOCKNAME(E)



NAME
       getsockname - get socket name

SYNOPSIS
       #include <sys/socket.h>

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

DESCRIPTION
       Getsockname  returns  the  current  name for the specified
       socket.  The namelen parameter 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 VALUE
       On  success,  zero is returned.  On error, -1 is returned,
       and errno is set appropriately.

ERRORS
       EBADF  The argument s is not a valid descriptor.

       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 parameter points to memory not in a valid
              part of the process address space.

CONFORMING TO
       SVr4, 4.4BSD (the getsockname function  call  appeared  in
       4.2BSD).  SVr4 documents additional ENOMEM and ENOSR error
       codes.

NOTE
       The third argument of getsockname is in reality an `int *'
       (and this is what BSD 4.* and libc4 and libc5 have).  Some
       POSIX confusion resulted in the  present  socklen_t.   The
       draft  standard  has  not  been  adopted  yet,  but glibc2
       already follows  it  and  also  has  socklen_t.  See  also
       accept(t).
