| SO_DEBUG |
Reports whether debugging information is being recorded.
|
int
|
| SO_BROADCAST |
Reports whether transmission of broadcast messages is supported.
|
int
|
| SO_REUSEADDR |
Reports whether local addresses can be reused.
|
int
|
| SO_KEEPALIVE |
Reports whether connections are kept active with periodic transmission
of messages. If the connected socket fails to respond to these messages,
the connection is broken and processes writing to that socket are notified
with a SIGPIPE signal.
|
int
|
| SO_LINGER |
Reports whether the socket
lingers on
socket_close() if data is present. By default,
when the socket is closed, it attempts to send all unsent data.
In the case of a connection-oriented socket,
socket_close() will wait for its peer to
acknowledge the data.
If l_onoff is non-zero and
l_linger is zero, all the
unsent data will be discarded and RST (reset) is sent to the
peer in the case of a connection-oriented socket.
On the other hand, if l_onoff is
non-zero and l_linger is non-zero,
socket_close() will block until all the data
is sent or the time specified in l_linger
elapses. If the socket is non-blocking,
socket_close() will fail and return an error.
|
array. The array will contain two keys:
l_onoff and
l_linger.
|
| SO_OOBINLINE |
Reports whether the socket
leaves out-of-band data inline.
|
int
|
| SO_SNDBUF |
Reports the size of the send buffer.
|
int
|
| SO_RCVBUF |
Reports the size of the receive buffer.
|
int
|
| SO_ERROR |
Reports information about error status and clears it.
|
int (cannot be set by socket_set_option())
|
| SO_TYPE |
Reports the socket
type (e.g.
SOCK_STREAM).
|
int (cannot be set by socket_set_option())
|
| SO_DONTROUTE |
Reports whether outgoing messages bypass the standard routing facilities.
|
int
|
| SO_RCVLOWAT |
Reports the minimum number of bytes to process for socket
input operations.
|
int
|
| SO_RCVTIMEO |
Reports the timeout value for input operations.
|
array. The array will contain two keys:
sec which is the seconds part on the timeout
value and usec which is the microsecond part
of the timeout value.
|
| SO_SNDTIMEO |
Reports the timeout value specifying the amount of time that an output
function blocks because flow control prevents data from being sent.
|
array. The array will contain two keys:
sec which is the seconds part on the timeout
value and usec which is the microsecond part
of the timeout value.
|
| SO_SNDLOWAT |
Reports the minimum number of bytes to process for socket
output operations.
