Currently I'm using
make-process and it's
stderr argument which is a buffer.
After the process has exited I'd like to check if the
buffer-length is zero (no error output).
This doesn't work as I get an unhelpful
Process *my-process* stderr finished.
Is there a way to get the stderr output of a process without additional text?
(besides searching for the string literal and stripping it out which seems over-complicated).
To give some context, I want to treat any error output as an error for the command I'm calling, as the exit-code isn't always a reliable way of checking if an error occurred.
