int pcre_jit_exec(const pcre *code, const pcre_extra *extra, const char *subject, int length, int startoffset, int options, int *ovector, int ovecsize, pcre_jit_stack *jstack); int pcre16_jit_exec(const pcre16 *code, const pcre16_extra *extra, PCRE_SPTR16 subject, int length, int startoffset, int options, int *ovector, int ovecsize, pcre_jit_stack *jstack); int pcre32_jit_exec(const pcre32 *code, const pcre32_extra *extra, PCRE_SPTR32 subject, int length, int startoffset, int options, int *ovector, int ovecsize, pcre_jit_stack *jstack);
code Points to the compiled pattern extra Points to an associated pcre[16|32]_extra structure, or is NULL subject Points to the subject string length Length of the subject string, in bytes startoffset Offset in bytes in the subject at which to start matching options Option bits ovector Points to a vector of ints for result offsets ovecsize Number of elements in the vector (a multiple of 3) jstack Pointer to a JIT stack
The allowed options are:
PCRE_NOTBOL Subject string is not the beginning of a line PCRE_NOTEOL Subject string is not the end of a line PCRE_NOTEMPTY An empty string is not a valid match PCRE_NOTEMPTY_ATSTART An empty string at the start of the subject is not a valid match PCRE_NO_UTF16_CHECK Do not check the subject for UTF-16 validity (only relevant if PCRE_UTF16 was set at compile time) PCRE_NO_UTF32_CHECK Do not check the subject for UTF-32 validity (only relevant if PCRE_UTF32 was set at compile time) PCRE_NO_UTF8_CHECK Do not check the subject for UTF-8 validity (only relevant if PCRE_UTF8 was set at compile time) PCRE_PARTIAL ) Return PCRE_ERROR_PARTIAL for a partial PCRE_PARTIAL_SOFT ) match if no full matches are found PCRE_PARTIAL_HARD Return PCRE_ERROR_PARTIAL for a partial match if that is found before a full match
However, the PCRE_NO_UTF[8|16|32]_CHECK options have no effect, as this check is never applied. For details of partial matching, see the pcrepartial page. A pcre_extra structure contains the following fields:
flags Bits indicating which fields are set study_data Opaque data from pcre[16|32]_study() match_limit Limit on internal resource use match_limit_recursion Limit on internal recursion depth callout_data Opaque data passed back to callouts tables Points to character tables or is NULL mark For passing back a *MARK pointer executable_jit Opaque data from JIT compilation
The flag bits are PCRE_EXTRA_STUDY_DATA, PCRE_EXTRA_MATCH_LIMIT, PCRE_EXTRA_MATCH_LIMIT_RECURSION, PCRE_EXTRA_CALLOUT_DATA, PCRE_EXTRA_TABLES, PCRE_EXTRA_MARK and PCRE_EXTRA_EXECUTABLE_JIT.
There is a complete description of the PCRE native API in the pcreapi page and a description of the JIT API in the pcrejit page.
