Add a module function to open a file descriptor connected to a pipe. 2020-03-26T20:47:25+00:00 Philipp Stephani 2020-03-26T16:22:25+00:00 d28b00476890f791a89b65007e5f20682b3eaa0d A common complaint about the module API is that modules can't communicate asynchronously with Emacs. While it isn't possible to call arbitrary Emacs functions asynchronously, writing to a pipe should always be fine and is a pretty low-hanging fruit.
