Variants

Capability = 0

Requests that the other side provide a list of supported versions and capabilities.

Version = 1

Requests a specific version and capabilities.

This request aborts all other in-flight requests by this sender. Consequently, it should be sent at the beginning of the connection right after a successful Capability message.

Authentication is not required for this message.

Ping = 2

Indicates a no-op request which should always be successful.

Authentication is not required for this message.

Authenticate = 3

Requests authentication.

This request aborts all other in-flight requests by this sender. Consequently, it should be sent at the beginning of the connection right after a successful Capability message.

Authentication is not required for this message (obviously).

Continue = 4

Continue an in-progress request.

This request can be used to continue an operation when the Continuation response is provided.

Abort = 5

Abort an in-progress request.

This request can be used to abort an operation when the Continuation response is provided.

CloseAlert = 4_096

Indicates a graceful shutdown.

Authentication is not required for this message.

CreateChannel = 65_536

Requests a channel to be created.

DeleteChannel = 65_537

Requests a channel to be deleted.

This request is made from the client to the server to terminate the connection.

ReadChannel = 65_538

Requests a read on the channel.

WriteChannel = 65_539

Requests a write on the channel.

PollChannel = 65_540

Requests the status of the selectors on the channel.

PingChannel = 65_541

Requests the status of the object on the other end of the channel.

For command channels, this can be used to check if the child has exited.

DetachChannelSelector = 65_553

ChannelMetadataNotification = 69_632

Provides notification of some sort of metadata condition on the channel.

For command channels, this is used by the server to notify the client that the process has terminated.

CreateExtensionRange = 131_072

Allocates a range of IDs for an extension.

DeleteExtensionRange = 131_073

Deallocates a range of IDs for an extension.

ListExtensionRanges = 131_074

Lists all allocated ranges of IDs for extensions.

OpenStore = 196_608

Open a store and associate an ID with it.

CloseStore = 196_609

Close a store and associate an ID with it.

ListStoreElements = 196_610

Lists all elements of a given type in the given store.

AcquireStoreElement = 196_611

Acquire a handle to an element in the given store.

CloseStoreElement = 196_612

Release the handle of a store element.

AuthenticateStoreElement = 196_613

Authenticate to a store element if that’s required to open it.

CreateStoreElement = 196_614

Create a store element.

DeleteStoreElement = 196_615

Delete a store element.

UpdateStoreElement = 196_616

Update a store element.

ReadStoreElement = 196_617

Read a store element.

RenameStoreElement = 196_618

Rename a store element.

CopyStoreElement = 196_619

Copy a store element.

SearchStoreElements = 196_620

Search store elements.

ReadServerContext = 262_144

Read a server context.

WriteServerContext = 262_145

Write a server context.
