This may be useful, for example, if there are interesting strings
or pre-compiled regular expressions stored there.
- It is also possible to access fix descriptions by using the
- index of a known fix, "my_fix_name" for example:
-
- tFixDesc* p_desc = fixDescList + MY_FIX_NAME_FIXIDX;
- tTestDesc* p_tlist = p_desc->p_test_desc;
-
- regexec (p_tlist->p_test_regex, ...)
