SYNOPSIS

12       pcre *pcre_compile2(const char *pattern, int options,
13            int *errorcodeptr,

DESCRIPTION

18
19       This  function  compiles a regular expression into an internal form. It
20       is the same as pcre_compile(), except for the addition  of  the  error‐
21       codeptr argument. The arguments are:
22
23
24         pattern       A zero-terminated string containing the
25                         regular expression to be compiled
26         options       Zero or more option bits
27         errorcodeptr  Where to put an error code
28         errptr        Where to put an error message
29         erroffset     Offset in pattern where error was found
30         tableptr      Pointer to character tables, or NULL to
31                         use the built-in default
32
33       The option bits are:
34
35         PCRE_ANCHORED         Force pattern anchoring
36         PCRE_AUTO_CALLOUT     Compile automatic callouts
37         PCRE_CASELESS         Do caseless matching
38         PCRE_DOLLAR_ENDONLY   $ not to match newline at end
39         PCRE_DOTALL           . matches anything including NL
40         PCRE_DUPNAMES         Allow duplicate names for subpatterns
41         PCRE_EXTENDED         Ignore white space and # comments
42         PCRE_EXTRA            PCRE extra features
43                                 (not much use currently)
44         PCRE_FIRSTLINE        Force matching to be before newline
45         PCRE_MULTILINE        ^ and $ match newlines within data
46         PCRE_NEWLINE_ANY      Recognize any Unicode newline sequence
47         PCRE_NEWLINE_ANYCRLF  Recognize CR, LF, and CRLF as newline sequences
48         PCRE_NEWLINE_CR       Set CR as the newline sequence
49         PCRE_NEWLINE_CRLF     Set CRLF as the newline sequence
50         PCRE_NEWLINE_LF       Set LF as the newline sequence
51         PCRE_NO_AUTO_CAPTURE  Disable numbered capturing paren-
52                                 theses (named ones available)
53         PCRE_UNGREEDY         Invert greediness of quantifiers
54         PCRE_UTF8             Run in UTF-8 mode
55         PCRE_NO_UTF8_CHECK    Do not check the pattern for UTF-8
56                                 validity (only relevant if
57                                 PCRE_UTF8 is set)
58
59       PCRE  must  be  built  with UTF-8 support in order to use PCRE_UTF8 and
60       PCRE_NO_UTF8_CHECK.
61
62       The yield of the function is a pointer to a private data structure that
63       contains  the  compiled pattern, or NULL if an error was detected. Note
64       that compiling regular expressions with one version  of  PCRE  for  use
65       with  a  different  version  is  not  guaranteed  to work and may cause
66       crashes.
67
68       There is a complete description of the PCRE native API in  the  pcreapi
69       page and a description of the POSIX API in the pcreposix page.
