14.1.3.1 Saving Data on Unexpected Exits
If Octave for some reason exits unexpectedly it will by default save the
variables available in the workspace to a file in the current directory.
By default this file is named ‘octave-core’ and can be loaded
into memory with the load
command. While the default behaviour
most often is reasonable it can be changed through the following
functions.
- Built-in Function: val = crash_dumps_octave_core ()
- Built-in Function: old_val = crash_dumps_octave_core (new_val)
- Query or set the internal variable that controls whether Octave tries
to save all current variables to the file ‘octave-core’ if it
crashes or receives a hangup, terminate or similar signal.
See also octave_core_file_limit, octave_core_file_name, octave_core_file_options
- Built-in Function: val = sighup_dumps_octave_core ()
- Built-in Function: old_val = sighup_dumps_octave_core (new_val)
- Query or set the internal variable that controls whether Octave tries to save all current variables to the file ‘octave-core’ if it receives a hangup signal.
- Built-in Function: val = sigterm_dumps_octave_core ()
- Built-in Function: old_val = sigterm_dumps_octave_core (new_val)
- Query or set the internal variable that controls whether Octave tries to save all current variables to the file ‘octave-core’ if it receives a terminate signal.
- Built-in Function: val = octave_core_file_options ()
- Built-in Function: old_val = octave_core_file_options (new_val)
- Query or set the internal variable that specifies the options used for
saving the workspace data if Octave aborts. The value of
octave_core_file_options
should follow the same format as the options for thesave
function. The default value is Octave's binary format.See also crash_dumps_octave_core, octave_core_file_name, octave_core_file_limit
- Built-in Function: val = octave_core_file_limit ()
- Built-in Function: old_val = octave_core_file_limit (new_val)
- Query or set the internal variable that specifies the maximum amount
of memory (in kilobytes) of the top-level workspace that Octave will
attempt to save when writing data to the crash dump file (the name of
the file is specified by octave_core_file_name). If
octave_core_file_options flags specify a binary format,
then octave_core_file_limit will be approximately the maximum
size of the file. If a text file format is used, then the file could
be much larger than the limit. The default value is -1 (unlimited)

- Built-in Function: val = octave_core_file_name ()
- Built-in Function: old_val = octave_core_file_name (new_val)
- Query or set the internal variable that specifies the name of the file
used for saving data from the top-level workspace if Octave aborts.
The default value is
‘octave-core’
