GETSOCKNAME(2)							System Calls Manual						    GETSOCKNAME(2)

NAME

       getsockname - get socket name

SYNOPSIS

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

DIAGNOSTICS

       A 0 is returned if the call succeeds, -1 if it fails.

ERRORS

       The call succeeds unless:

       [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.

SEE ALSO

       bind(2), socket(2)

BUGS

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

NAME

       getpeername - get name of connected peer

SYNOPSIS

       getpeername(s, name, namelen)
       int s;
       struct sockaddr *name;
       int *namelen;

DESCRIPTION

       Getpeername  returns  the  name	of  the peer connected to socket s.  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).  The name is truncated if the buffer pro-
       vided is too small.

DIAGNOSTICS

       A 0 is returned if the call succeeds, -1 if it fails.

ERRORS

       The call succeeds unless:

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

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

       [ENOTCONN]     The socket is not connected.

       [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.
