# fail_after -- exits openMSX after timeout.
|
|
#
|
|
# Typically used in combination with the MSX-DOS 'omsxctl.com' utility.
|
|
#
|
|
# Adds two commands to openMSX;
|
|
#
|
|
# 'fail_after <timeout> [timeunit] [fail_id] [fail_code]'
|
|
# Schedules an openMSX exit after the timeout.
|
|
# This can be canceled by requesting a timeout of 0 or new timeout.
|
|
# The timeunit can be selected between (msx)'time' and (host)'realtime'.
|
|
# The fail_id can be used to differentiate between multiple fail_after commands.
|
|
# The failure exit code can be given too.
|
|
#
|
|
# 'fail_after_exit [fail_id] [fail_code]'
|
|
# Exits openMSX with an failure exit code and if the FAIL_AFTER_PATH is
|
|
# set it also creates a screenshot named from the failure id.
|
|
#
|
|
# Supported environment variables by this script;
|
|
#
|
|
# BOOT_WATCHDOG=30
|
|
# Enables the boot watchdog timer which will exit openMSX after the timeout(in seconds).
|
|
# To cancel this timer give an `fail_after 0` or any new fail_after command.
|
|
# (exits with status 124 see `man timeout`)
|
|
