    SYNOPSIS

    
           #include <pcre.h>
    
           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,

    DESCRIPTION

    
           This  function matches a compiled regular expression that has been suc-
           cessfully studied with one of the JIT options 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  pcre_exec()  applies.  It returns offsets to captured substrings.
           Its arguments are:
    
             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
    
             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.
