CLTP sockets are connectionless, and are ! 34: normally used with the ! 35: .I sendto ! 36: and ! 37: .IR recvfrom ! 38: calls, though the ! 39: .IR connect (2) ! 40: call may also be used to fix the destination for future ! 41: packets (in which case the ! 42: .IR recv (2) ! 43: or ! 44: .IR read (2) ! 45: and ! 46: .IR send (2) ! 47: or ! 48: .IR write(2) ! 49: system calls may be used). ! 50: .PP ! 51: CLTP address formats are identical to those used by TP. ! 52: In particular CLTP provides a service selector in addition ! 53: to the normal ISO NSAP. Note that the CLTP selector ! 54: space is separate from the TP selector space (i.e. a CLTP selector ! 55: may not be \*(lqconnected\*(rq to a TP selector). ! 56: .PP ! 57: Options at the CLNP network level may be used with CLTP; see ! 58: .IR clnp (4). ! 59: .SH DIAGNOSTICS ! 60: A socket operation may fail with one of the following errors returned: ! 61: .TP 15 ! 62: [EISCONN] ! 63: when trying to establish a connection on a socket which ! 64: already has one, or when trying to send a datagram with the destination ! 65: address specified and the socket is already connected; ! 66: .TP 15 ! 67: [ENOTCONN] ! 68: when trying to send a datagram, but ! 69: no destination address is specified, and the socket hasn't been ! 70: connected; ! 71: .TP 15 ! 72: [ENOBUFS] ! 73: when the system runs out of memory for ! 74: an internal data structure; ! 75: .TP 15 ! 76: [EADDRINUSE] ! 77: when an attempt ! 78: is made to create a socket with a selector which has already been ! 79: allocated; ! 80: .TP 15 ! 81: [EADDRNOTAVAIL] ! 82: when an attempt is made to create a ! 83: socket with a network address for which no network interface ! 84: exists. ! 85: .SH SEE ALSO ! 86: getsockopt(2), recv(2), send(2), socket(2), intro(4), iso(4), clnp(4)
