Section (3) pcre2_get_mark
PCRE2 — Perl-compatible regular expressions (revised API)
After a call of
pcre2_match() that was passed the match
block that is this function_zsingle_quotesz_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 compiled 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.
