-.SH DESCRIPTION
-.rs
-.sp
-This function returns information about a compiled pattern. Its arguments are:
-.sp
-  \fIcode\fP                      Compiled regular expression
-  \fIextra\fP                     Result of \fBpcre[16|32]_study()\fP or NULL
-  \fIwhat\fP                      What information is required
-  \fIwhere\fP                     Where to put the information
-.sp
-The following information is available:
-.sp
-  PCRE_INFO_BACKREFMAX      Number of highest back reference
-  PCRE_INFO_CAPTURECOUNT    Number of capturing subpatterns
-  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_MATCHEMPTY      Return 1 if the pattern can match an empty string,
-                               0 otherwise
-  PCRE_INFO_MATCHLIMIT      Match limit if set, otherwise PCRE_RROR_UNSET
-  PCRE_INFO_MAXLOOKBEHIND   Length (in characters) of the longest lookbehind assertion
-  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
-  PCRE_INFO_FIRSTCHARACTERFLAGS Returns
-                                  1 if there is a first data character set, which can
-                                    then be retrieved using PCRE_INFO_FIRSTCHARACTER,
-                                  2 if the first character is at the start of the data
-                                    string or after a newline, and
-                                  0 otherwise
-  PCRE_INFO_RECURSIONLIMIT    Recursion limit if set, otherwise PCRE_ERROR_UNSET
-  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_REQUIREDCHAR); 0 otherwise
