20 passing control to the caller of PCRE in the middle of pattern matching. The
53 Automatic callouts can be used for tracking the progress of pattern matching.
81 This indicates that when matching [bc] fails, there is no backtracking into a+
97 This time, when matching [bc] fails, the matcher backtracks into a+ and tries
105 PCRE knows that any matching string must contain the letter "d". If the subject
106 string is "abyz", the lack of "d" means that matching doesn't ever start, and
110 If the pattern is studied, PCRE knows the minimum length of a matching string,
