There can be many reasons for an error and a parent process will often know what specifically went wrong with a child process. As such 0 is used for success and 1 to 255 provides flexibility for failure reason(s).
For example a child process could return:
1File not found2User not authorized3File locked by another process4Connection not active5Configuration incomplete6Process cancelled by user
etc, etc.
