[PATCH 2/4] find: remove redundant function error_severity and avoid magic numbers |
|
Date: |
Mon, 20 Sep 2021 00:07:08 +0200 |
The struct state field exit_status is only set to 0 (EXIT_SUCCESS) or
to 1 (EXIT_FAILURE) throughout the code.
Therefore, remove the more complicated wrapper function error_severity
which was only used in very few cases anyway.
While at it, replace the above magic numbers by EXIT_OKAY/EXIT_SUCCESS.
* find/defs.h (error_severity): Remove.
* find/util.c (error_severity): Remove, and update all callers by replacing
it by the direct assignment to state.exit_status.
(get_statinfo): Use the above better names.
(report_file_err): Likewise.
* find/exec.c (launch): Likewise.
* find/ftsfind.c (consider_visiting): Likewise.
(find): Likewise.
(process_all_startpoints): Likewise.
(main): Likewise.
* find/pred.c (pred_delete): Likewise.
(pred_empty): Likewise.
(match_lname): Likewise.
(pred_xtype): Likewise.
* find/print.c (do_fprintf): Likewise.
