DESCRIPTION
This function matches a compiled regular expression that has been successfully processed by the JIT compiler against a given subject string, using a matching algorithm that is similar to Perl’s. It is a "fast path" interface to JIT, and it bypasses some of the sanity checks that pcre2_match() applies.
In UTF mode, the subject string is not checked for UTF validity. Unless PCRE2_MATCH_INVALID_UTF was set when the pattern was compiled, passing an invalid UTF string results in undefined behaviour. Your program may crash or loop or give wrong results. In the absence of PCRE2_MATCH_INVALID_UTF you should only call pcre2_jit_match() in UTF mode if you are sure the subject is valid.
The arguments for pcre2_jit_match() are exactly the same as for pcre2_match() , except that the subject string must be specified with a length; PCRE2_ZERO_TERMINATED is not supported.
The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY, PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported options are ignored.
The return values are the same as for pcre2_match() plus PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requested that was not compiled. For details of partial matching, see the pcre2partial page.
There is a complete description of the PCRE2 native API in the pcre2api page and a description of the JIT API in the pcre2jit page.
