From 705c09bb3cdffb141986598ad4ff9c9b0a66c3bd Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Fri, 5 Apr 2024 00:09:30 -0700 Subject: tools subcmd: Add check_if_command_finished() Add non-blocking function to check if a 'struct child_process' has completed. If the process has completed the exit code is stored in the 'struct child_process' so that finish_command() returns it.
