The es_copy_message function is deprecated and there are no alternatives provided.

https://developer.apple.com/documentation/endpointsecurity/3228861-es_copy_message

Currently, we copy incoming messages so that we can respond to messages later on a different dispatch queue/thread.

Is there a change in ownership of incoming messages or is there something that I am missing here?

From the header file

/**

Retains an esmessaget, returning a non-const pointer to the given esmessaget for compatibility with

* existing code.

* @warning It is invalid to attempt to write to the returned esmessaget, despite being non-const, and

* doing so will result in a crash.

* @deprecated Use esretainmessage to retain a message.

*

@param msg The message to be retained

* @return non-const pointer to the retained esmessaget.

* @brief The caller must release the memory with es_free_message

The formatting got all messed up, best to just look at the header file in Xcode 12.2 beta 2 where I got this

Thanks mdolan! Looks like online documentation doesn't have all the details, I will get the beta and refer to the headers.
