k_nSteamNetworkingSend_AutoRestartBrokenSession

When sending a message using ISteamNetworkingMessages, automatically re-establish a broken session, without returning k_EResultNoConnection. Without this flag, if you attempt to send a message, and the session was proactively closed by the peer, or an error occurred that disrupted communications, then you must close the session using ISteamNetworkingMessages::CloseSessionWithUser before attempting to send another message. (Or you can simply add this flag and retry.) In this way, the disruption cannot go unnoticed, and a more clear order of events can be ascertained. This is especially important when reliable messages are used, since if the connection is disrupted, some of those messages will not have been delivered, and it is in general not possible to know which. Although a SteamNetworkingMessagesSessionFailed_t callback will be posted when an error occurs to notify you that a failure has happened, callbacks are asynchronous, so it is not possible to tell exactly when it happened. And because the primary purpose of ISteamNetworkingMessages is to be like UDP, there is no notification when a peer closes the session. If you are not using any reliable messages (e.g. you are using ISteamNetworkingMessages exactly as a transport replacement for UDP-style datagrams only), you may not need to know when an underlying connection fails, and so you may not need this notification.

Declaration
public const int k_nSteamNetworkingSend_AutoRestartBrokenSession = 32
Field Value
Type Description
int

k_nSteamNetworkingSend_NoDelay

If the message cannot be sent very soon (because the connection is still doing some initial handshaking, route negotiations, etc), then just drop it. This is only applicable for unreliable messages. Using this flag on reliable messages is invalid.

Declaration
public const int k_nSteamNetworkingSend_NoDelay = 4
Field Value
Type Description
int

k_nSteamNetworkingSend_NoNagle

Disable Nagle's algorithm. By default, Nagle's algorithm is applied to all outbound messages. This means that the message will NOT be sent immediately, in case further messages are sent soon after you send this, which can be grouped together. Any time there is enough buffered data to fill a packet, the packets will be pushed out immediately, but partially-full packets not be sent until the Nagle timer expires. See ISteamNetworkingSockets::FlushMessagesOnConnection, ISteamNetworkingMessages::FlushMessagesToUser NOTE: Don't just send every message without Nagle because you want packets to get there quicker. Make sure you understand the problem that Nagle is solving before disabling it. If you are sending small messages, often many at the same time, then it is very likely that it will be more efficient to leave Nagle enabled. A typical proper use of this flag is when you are sending what you know will be the last message sent for a while (e.g. the last in the server simulation tick to a particular client), and you use this flag to flush all messages.

Declaration
public const int k_nSteamNetworkingSend_NoNagle = 1
Field Value
Type Description
int

k_nSteamNetworkingSend_Reliable

Reliable message send. Can send up to k_cbMaxSteamNetworkingSocketsMessageSizeSend bytes in a single message. Does fragmentation/re-assembly of messages under the hood, as well as a sliding window for efficient sends of large chunks of data. The Nagle algorithm is used. See notes on k_ESteamNetworkingSendType_Unreliable for more details. See k_ESteamNetworkingSendType_ReliableNoNagle, ISteamNetworkingSockets::FlushMessagesOnConnection, ISteamNetworkingMessages::FlushMessagesToUser Migration note: This is NOT the same as k_EP2PSendReliable, it's more like k_EP2PSendReliableWithBuffering

Declaration
public const int k_nSteamNetworkingSend_Reliable = 8
Field Value
Type Description
int

k_nSteamNetworkingSend_ReliableNoNagle

Send a message reliably, but bypass Nagle's algorithm. Migration note: This is equivalent to k_EP2PSendReliable

Declaration
public const int k_nSteamNetworkingSend_ReliableNoNagle = 9
Field Value
Type Description
int

k_nSteamNetworkingSend_Unreliable

Flags used to set options for message sending Send the message unreliably. Can be lost. Messages can be larger than a single MTU (UDP packet), but there is no retransmission, so if any piece of the message is lost, the entire message will be dropped. The sending API does have some knowledge of the underlying connection, so if there is no NAT-traversal accomplished or there is a recognized adjustment happening on the connection, the packet will be batched until the connection is open again. Migration note: This is not exactly the same as k_EP2PSendUnreliable! You probably want k_ESteamNetworkingSendType_UnreliableNoNagle

Declaration
public const int k_nSteamNetworkingSend_Unreliable = 0
Field Value
Type Description
int

k_nSteamNetworkingSend_UnreliableNoDelay

Send an unreliable message, but if it cannot be sent relatively quickly, just drop it instead of queuing it. This is useful for messages that are not useful if they are excessively delayed, such as voice data. NOTE: The Nagle algorithm is not used, and if the message is not dropped, any messages waiting on the Nagle timer are immediately flushed. A message will be dropped under the following circumstances:

  • the connection is not fully connected. (E.g. the "Connecting" or "FindingRoute" states)
  • there is a sufficiently large number of messages queued up already such that the current message will not be placed on the wire in the next ~200ms or so. If a message is dropped for these reasons, k_EResultIgnored will be returned.
Declaration
public const int k_nSteamNetworkingSend_UnreliableNoDelay = 5
Field Value
Type Description
int

k_nSteamNetworkingSend_UnreliableNoNagle

Send a message unreliably, bypassing Nagle's algorithm for this message and any messages currently pending on the Nagle timer. This is equivalent to using k_ESteamNetworkingSend_Unreliable and then immediately flushing the messages using ISteamNetworkingSockets::FlushMessagesOnConnection or ISteamNetworkingMessages::FlushMessagesToUser. (But using this flag is more efficient since you only make one API call.)

Declaration
public const int k_nSteamNetworkingSend_UnreliableNoNagle = 1
Field Value
Type Description
int

k_nSteamNetworkingSend_UseCurrentThread

By default, message sending is queued, and the work of encryption and talking to the operating system sockets, etc is done on a service thread. This is usually a a performance win when messages are sent from the "main thread". However, if this flag is set, and data is ready to be sent immediately (either from this message or earlier queued data), then that work will be done in the current thread, before the current call returns. If data is not ready to be sent (due to rate limiting or Nagle), then this flag has no effect. This is an advanced flag used to control performance at a very low level. For most applications running on modern hardware with more than one CPU core, doing the work of sending on a service thread will yield the best performance. Only use this flag if you have a really good reason and understand what you are doing. Otherwise you will probably just make performance worse.
