Function Documentation

jsOptions_Init()

NATS_EXTERN natsStatus jsOptions_Init

(

jsOptions *

opts

)

Use this before setting specific stream context options and passing it to JetStream APIs.

Parameters

opts	the pointer to the jsOptions to initialize.

natsConnection_JetStream()

NATS_EXTERN natsStatus natsConnection_JetStream	(	jsCtx **	js,
		natsConnection *	nc,
		jsOptions *	opts )

A JetStream context is used for messaging and assets management.

Since the underlying NATS connection is used for communication, the NATS connection should stay valid while using the JetStream context. That is, do not close/destroy the NATS connection before destroying the JetStream context.

Note

When done, the context should be destroyed to release memory.

Parameters

js	the location where to store the pointer to the newly created jsCtx object.
nc	the pointer to the natsConnection object from which to get the JetStream context.
opts	the pointer to the jsOptions object, possibly NULL.

jsCtx_Destroy()

NATS_EXTERN void jsCtx_Destroy

(

jsCtx *

js

)

Releases memory used by the context object.

Parameters

js	the pointer to the jsCtx object to destroy.
