PCRE2_SPTR pcre2_get_mark(pcre2_match_data *match_data);
After a call of pcre2_match() that was passed the match block that is
this function's argument, this function returns a pointer to the last
(*MARK), (*PRUNE), or (*THEN) name that was encountered during the
matching process. The name is zero-terminated, and is within the com-
piled pattern. The length of the name is in the preceding code unit. If
no name is available, NULL is returned.
After a successful match, the name that is returned is the last one on
the matching path. After a failed match or a partial match, the last
encountered name is returned.
There is a complete description of the PCRE2 native API in the pcre2api
page and a description of the POSIX API in the pcre2posix page.
