What is GetLinkedBinding (and its derivatives--process._linkedBinding) purpose?

void GetLinkedBinding(const FunctionCallbackInfo<Value>& args) {

What is the purpose of the above function? Is it for loading user-defined NAPI modules?

Hey @anonhostpi,
So, the function void GetLinkedBinding(const FunctionCallbackInfo<Value>& args) is a callback function used in a Node.js native addon. This is not for NAPI, the function is typically used to handle calls from JavaScript to native code

Hi! No, they are add-ons, they are not part of the Node.js executable. The Node.js executable just provides the interface for them.

[anonhostpi]

So they would typically take the form of a shared (dynamic link) library and not statically linked, correct?

[juanarbol]

According to the documentation.

Addons are dynamically-linked shared objects written in C++. The require() function can load addons as ordinary Node.js modules. Addons provide an interface between JavaScript and C/C++ libraries.
