NAME    [Toc]    [Back]

       getsockname - get socket name

SYNOPSIS    [Toc]    [Back]

       #include <sys/socket.h>

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

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       On  success,  zero is returned.	On error, -1 is returned, and errno is
       set appropriately.

ERRORS    [Toc]    [Back]

       EBADF  The argument s is not a valid descriptor.

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

       ENOBUFS    [Toc]    [Back]
	      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    [Toc]    [Back]

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

NOTE    [Toc]    [Back]

       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(2).
