jsep | JavaScript Expression Parser | Parser library

I see in the W3C WebRTC specs that RTCSessionDescription.toJSON() is supported. I also see support for it on Mozilla website. Question: Is this support available across all other browsers? Is there any standard on the JSON conversion itself. I think the specs are silent about any details on the SDP to JSON conversion other than a one-liner reference to this support. JSEP specs also does not throw any additional light either.

SDP is a simple key-value format. There can be, for example, multiple entries for the same key. Does JSON conversion represent this as an array of values? Is the order maintained? Order in SDP is important. How is this taken care of in JSON conversion where properties have no significance in terms of their position in the object.

After attaching videoroom plugin to Janus, in "success" callback i send synchronous message to it

I'm working on getting https://github.com/donmccurdy/expression-eval to properly support expressions containing this.

The module defines a function:

I have a caller function that invokes another function that send a HTTP POST with parameters. Now i want that this called function blocks execution until there is its "success" (so when its HTTP POST has been done).

This is my logical code:

so i am using jansson library and i want to set a value: json_object_set_new(event, "error_code", json_integer(response->error_code));

The problem is that, i need to free response struct, but still use the value i have set in json_object_set_new.

Should i copy the value from response->error_code and how can i do that?
