From c6a8697800376a02b868cdea8fc1bf55f12798f1 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Mon, 16 Dec 2019 23:14:45 +0100 Subject: Introduce helper functions for safe fork+exec of processes In some situations, we want to execute an external shell command in a non-blocking way. Similar to 'system', but without waiting for the child to complete. We also want to close all file descriptors ahead of the exec() and filter + modify the environment.
