SockOpt

The Maximum Transfer Unit

If sending is blocking

If receiving is blocking

Initial Sequence Number (valid only after srt_connect or srt_accept-ed sockets)

Flight flag size (window size)

Maximum buffer in sending queue

UDT receiving buffer size

Waiting for unsent data when closing

UDP sending buffer size

UDP receiving buffer size

Rendezvous connection mode

SrtSocket.send timeout

SrtSocket.recv timeout

Reuse an existing port or create a new one

Maximum bandwidth (bytes per second) that the connection can use

Current socket state, see UDTSTATUS, read only

Current available events associated with the socket

Size of data in the sending buffer

Size of data available for recv

Sender mode (independent of conn mode), for encryption, tsbpd handshake.

Enable/Disable TsbPd. Enable -> Tx set origin timestamp, Rx deliver packet at origin time + delay

NOT RECOMMENDED. SET: to both RCVLATENCY and PEERLATENCY. GET: same as RCVLATENCY.

Estimated input stream rate.

Minimum estimate of input stream rate.

MaxBW ceiling based on % over input stream rate. Applies when UDT_MAXBW=0 (auto).

Crypto PBKDF2 Passphrase size (0,10..64) 0:disable crypto

Crypto key len in bytes {16,24,32} Default: 16 (128-bit)

Key Material exchange status (UDT_SRTKmState)

IP Time To Live (passthru for system sockopt IPPROTO_IP/IP_TTL)

IP Type of Service (passthru for system sockopt IPPROTO_IP/IP_TOS)

Enable receiver pkt drop

Extra delay towards latency for sender TLPKTDROP decision (-1 to off)

Enable receiver to send periodic NAK reports

Local SRT Version

Peer SRT Version (from SRT Handshake)

Connect timeout in msec. Caller default: 3000, rendezvous (x 10)

Enable or disable drift tracer

(GET) the current state of the encryption at the peer side

(GET) the current state of the encryption at the agent side

Maximum possible packet reorder tolerance (number of packets to receive after loss to send lossreport)

TsbPd receiver delay (mSec) to absorb burst of missed packet retransmission

Minimum value of the TsbPd receiver delay (mSec) for the opposite side (peer)

Minimum SRT version needed for the peer (peers with less version will get connection reject)

A string set to a socket and passed to the listener's accepted socket

Congestion controller type selection

In File mode, use message API (portions of data with boundaries)

Maximum payload size sent in one UDP packet (0 if unlimited)

Transmission type (set of options required for given transmission type)

After sending how many packets the encryption key should be flipped to the new key

How many packets before key flip the new key is annnounced and after key flip the old one decommissioned

Connection to be rejected or quickly broken when one side encryption set or bad password

IPV6_V6ONLY mode

Peer-idle timeout (max time of silence heard from peer) in ms

Forward the BINDTODEVICE option on socket (pass packets only from that device)

Add and configure a packet filter

An option to select packet retransmission algorithm

Returns a representation of an immutable list of all enum entries, in the order they're declared.

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Returns an array containing the constants of this enum type, in the order they're declared.
