Field Description
•
SO_REUSEADDR —Allows the local address reuse.
•
SO_KEEPALIVE —Requires the protocol to test whether the
connection is still alive.
•
SO_DONTROUTE —Bypasses the routing table query for outgoing
packets because the destination is in a directly connected network.
•
SO_BROADCAST —Supports broadcast packets.
•
SO_LINGER —Closes the socket. The system can still send remaining
data in the socket send buffer.
•
SO_OOBINLINE —Stores the out-of-band data in the input queue.
•
SO_REUSEPORT —Allows the local port reuse.
•
SO_NOSIGPIPE —Disables the socket from sending data. As a result,
a sigpipe cannot be established when a return failure occurs.
•
SO_TIMESTAMPNS —Has a similar function with the timestamp,
accurate to nanoseconds.
•
SO_KEEPALIVETIME —Sets a keepalive time. This option is
supported in TCP.
•
SO_FILTER —Supports setting the packet filter criterion. This option is
available for OSI Socket and RawIP.
•
N/A —No options are set.
Error Error code.
Receiving
buffer(cc/hiwat/lowat/state)
Displays receive buffer information in the following order:
•
cc —Used space.
•
hiwat —Maximum space.
•
lowat —Minimum space.
•
state —Buffer state:

CANTSENDMORE —Unable to send data to the peer.

CANTRCVMORE —Unable to receive data from the peer.

RCVATMARK —Receiving tag.

N/A —None of the above states.
Sending
buffer(cc/hiwat/lowat/state)

•
cc —Used space.
•
hiwat —Maximum space.
•
lowat —Minimum space.
•
state —Buffer state:

CANTSENDMORE —Unable to send data to the peer.

CANTRCVMORE —Unable to receive data from the peer.

RCVATMARK —Receiving tag.

N/A —None of the above states.
Type
Socket type:
•
1 — SOCK_STREAM . This socket uses TCP to provide reliable
transmission of byte streams.
•
2 — SOCK_DGRAM . This socket uses UDP to provide datagram
transmission.
•
3 — SOCK_RAW . This socket allows an application to change the next
upper-layer protocol header.
•
N/A —None of the above types.
Protocol Number of the protocol using the socket. 6 represents TCP.
Inpcb flags
Flags in the Internet PCB:
•
INP_RECVOPTS —Receives IPv6 options.
•
INP_RECVRETOPTS —Receives replied IPv6 options.
•
INP_RECVDSTADDR —Receives destination IPv6 address.
