pcre2_jit_match: Perl-compatible regular expressions (revised API)


PCRE2 - Perl-compatible regular expressions (revised API)


#include <pcre2.h>

int pcre2_jit_match(const pcre2_code *code, PCRE2_SPTR subject,
  PCRE2_SIZE length, PCRE2_SIZE startoffset,
  uint32_t options, pcre2_match_data *match_data,
  pcre2_match_context *mcontext);


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. Its arguments are exactly the same as for pcre2_match().

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 subject string is not checked for UTF validity.

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.
