       int pcre_fullinfo(const pcre *code, const pcre_extra *extra,
            int what, void *where);

       This  function  returns information about a compiled pattern. Its argu-
       ments are:

         code                      Compiled regular expression
         extra                     Result of pcre[16|32]_study() or NULL
         what                      What information is required
         where                     Where to put the information

         PCRE_INFO_DEFAULT_TABLES  Pointer to default tables
         PCRE_INFO_FIRSTBYTE       Fixed first data unit for a match, or
                                     -1 for start of string
                                        or after newline, or
                                     -2 otherwise
         PCRE_INFO_FIRSTTABLE      Table of first data units (after studying)
         PCRE_INFO_HASCRORLF       Return 1 if explicit CR or LF matches exist
         PCRE_INFO_JCHANGED        Return 1 if (?J) or (?-J) was used
         PCRE_INFO_JIT             Return 1 after successful JIT compilation
         PCRE_INFO_JITSIZE         Size of JIT compiled code
         PCRE_INFO_LASTLITERAL     Literal last data unit required
         PCRE_INFO_MINLENGTH       Lower bound length of matching strings
         PCRE_INFO_NAMECOUNT       Number of named subpatterns
         PCRE_INFO_NAMEENTRYSIZE   Size of name table entry
         PCRE_INFO_NAMETABLE       Pointer to name table
         PCRE_INFO_OKPARTIAL       Return 1 if partial matching can be tried
                                     (always returns 1 after release 8.00)
         PCRE_INFO_OPTIONS         Option bits used for compilation
         PCRE_INFO_SIZE            Size of compiled pattern
         PCRE_INFO_STUDYSIZE       Size of study data
         PCRE_INFO_FIRSTCHARACTER      Fixed first data unit for a match
                                         1 if there is a first data  character
       set, which can
                                           then     be     retrieved     using

         PCRE_INFO_REQUIREDCHAR      Literal last data unit required
         PCRE_INFO_REQUIREDCHARFLAGS  Returns  1 if the last data character is
       set (which can then
                                     be  retrieved  using  PCRE_INFO_REQUIRED-
       CHAR); 0 otherwise

       The  where  argument  must point to an integer variable, except for the
       following what values:

         PCRE_INFO_DEFAULT_TABLES  const unsigned char *
         PCRE_INFO_FIRSTTABLE      const unsigned char *
         PCRE_INFO_NAMETABLE       PCRE_SPTR16           (16-bit library)
         PCRE_INFO_NAMETABLE       PCRE_SPTR32           (32-bit library)
         PCRE_INFO_NAMETABLE       const unsigned char * (8-bit library)
         PCRE_INFO_OPTIONS         unsigned long int
         PCRE_INFO_SIZE            size_t
         PCRE_INFO_REQUIREDCHAR    uint32_t

       The yield of the function is zero on success or:

         PCRE_ERROR_NULL           the argument code was NULL
                                   the argument where was NULL
         PCRE_ERROR_BADMAGIC       the "magic number" was not found
         PCRE_ERROR_BADOPTION      the value of what was invalid

       There is a complete description of the PCRE native API in  the  pcreapi
       page and a description of the POSIX API in the pcreposix page.
