- code Compiled regular expression
- extra Result of pcre[16|32]_study() or NULL
- what What information is required
- where Where to put the information
-
-The following information is available:
-
- 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_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_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
-
-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_FIRSTCHARACTER uint32_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
