30 /* 0 for check-only mode, 1 for set-string mode */
32 /* 0 for error, 1 if succeed */
35 * The following 2 fields are ignored if set_string field is set to '0'
36 * (in check only mode).
38 * But they can still be ignored explicitly in set-string mode by:
39 * setting -1 to expected_type and setting NULL to expected_string.
41 * It's useful in a case of set-string mode but the expected result
42 * is a 'parsing error'.
45 const char *expected_string;
49 * Actually, the "loose" mode has been tested in
50 * those time-compare-cases, so we may not test it again.
