history: History List Management
2.3.2 History List Management
-----------------------------
These functions manage individual entries on the history list, or set
parameters managing the list itself.
-- Function: void add_history (const char *string)
Place STRING at the end of the history list. The associated data
field (if any) is set to 'NULL'.
-- Function: void add_history_time (const char *string)
Change the time stamp associated with the most recent history entry
to STRING.
-- Function: HIST_ENTRY * remove_history (int which)
Remove history entry at offset WHICH from the history. The removed
element is returned so you can free the line, data, and containing
structure.
-- Function: histdata_t free_history_entry (HIST_ENTRY *histent)
Free the history entry HISTENT and any history library private data
associated with it. Returns the application-specific data so the
caller can dispose of it.
-- Function: HIST_ENTRY * replace_history_entry (int which, const char
*line, histdata_t data)
Make the history entry at offset WHICH have LINE and DATA. This
returns the old entry so the caller can dispose of any
application-specific data. In the case of an invalid WHICH, a
'NULL' pointer is returned.
-- Function: void clear_history (void)
Clear the history list by deleting all the entries.
-- Function: void stifle_history (int max)
Stifle the history list, remembering only the last MAX entries.
-- Function: int unstifle_history (void)
Stop stifling the history. This returns the previously-set maximum
number of history entries (as set by 'stifle_history()'). The
value is positive if the history was stifled, negative if it
wasn't.
-- Function: int history_is_stifled (void)
Returns non-zero if the history is stifled, zero if it is not.
