System Functions (s and S) spt_sendx(2)
[ENETDOWN]
The local interface used to reach the destination is down.
[ENETUNREACH]
No route to the network or host is present.
[ENOBUFS] Not enough buffer space was available to complete the call. A retry at a later
time might succeed.
[ENOMEM] Required memory resources were not available. A retry at a later time might
succeed.
[ENOTCONN] The socket either is not connected or has not had the peer socket previously
specified.
[ENOTSOCK] The socket parameter does not refer to a socket.
[EOPNOTSUPP]
The specified value for the flags parameter is not supported for this socket type
or protocol.
[EPIPE] One of the following conditions occurred:
• An attempt was made to send a message on a socket that is shut down
for writing.
• An attempt was made to send a message on a connection-oriented socket
and the peer socket is closed or shut down for reading. The SIGPIPE
signal is also sent to the calling process.
[EWOULDBLOCK]
The socket’s file descriptor is marked nonblocking (O_NONBLOCK is set) and
the operation would block.
