395937 - js-ctypes initial landing

Status: RESOLVED FIXED

(Core :: js-ctypes, defect)

Description

Attachment: js-ctypes initial landing v1

js-ctypes is a ffi (Foreign Function Interface) component for JS/XPCOM.
js-ctypes allows developers to call functions in dlls/shared libraries directly
from JavaScript without the need to create binary XPCOM wrappers.

I wanted to get some feedback before landing this. Should you actually want to build from this patch, put the code in "mozilla/components/js-types" and it should build.

I'll also be attaching a simple example too.

FYI - nsNativeMethod::Execute needs more work to support _more_ native types for arguments and return types.

Does OS X use the linux implementation or is it not supported?

Also, I think many people would prefer "unsigned short" instead of PRUint16.

I do not currently support OSX, but the underlying libffi does support it. It needs to be added
