3 PCRE - Perl-compatible regular expressions
10 .B pcre *pcre_compile2(const char *\fIpattern\fP, int \fIoptions\fP,
12 .B int *\fIerrorcodeptr\fP,
14 .B const char **\fIerrptr\fP, int *\fIerroffset\fP,
16 .B const unsigned char *\fItableptr\fP);
21 This function compiles a regular expression into an internal form. It is the
22 same as \fBpcre_compile()\fP, except for the addition of the \fIerrorcodeptr\fP
23 argument. The arguments are:
26 \fIpattern\fR A zero-terminated string containing the
27 regular expression to be compiled
28 \fIoptions\fR Zero or more option bits
29 \fIerrorcodeptr\fP Where to put an error code
30 \fIerrptr\fR Where to put an error message
31 \fIerroffset\fR Offset in pattern where error was found
32 \fItableptr\fR Pointer to character tables, or NULL to
33 use the built-in default
37 PCRE_ANCHORED Force pattern anchoring
38 PCRE_AUTO_CALLOUT Compile automatic callouts
39 PCRE_BSR_ANYCRLF \eR matches only CR, LF, or CRLF
40 PCRE_BSR_UNICODE \eR matches all Unicode line endings
41 PCRE_CASELESS Do caseless matching
42 PCRE_DOLLAR_ENDONLY $ not to match newline at end
43 PCRE_DOTALL . matches anything including NL
44 PCRE_DUPNAMES Allow duplicate names for subpatterns
45 PCRE_EXTENDED Ignore whitespace and # comments
46 PCRE_EXTRA PCRE extra features
47 (not much use currently)
48 PCRE_FIRSTLINE Force matching to be before newline
49 PCRE_JAVASCRIPT_COMPAT JavaScript compatibility
50 PCRE_MULTILINE ^ and $ match newlines within data
51 PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
52 PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline
54 PCRE_NEWLINE_CR Set CR as the newline sequence
55 PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
56 PCRE_NEWLINE_LF Set LF as the newline sequence
57 PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
58 theses (named ones available)
59 PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
60 validity (only relevant if
62 PCRE_UCP Use Unicode properties for \ed, \ew, etc.
63 PCRE_UNGREEDY Invert greediness of quantifiers
64 PCRE_UTF8 Run in UTF-8 mode
66 PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and
67 PCRE_NO_UTF8_CHECK, and with UCP support if PCRE_UCP is used.
69 The yield of the function is a pointer to a private data structure that
70 contains the compiled pattern, or NULL if an error was detected. Note that
71 compiling regular expressions with one version of PCRE for use with a different
72 version is not guaranteed to work and may cause crashes.

78 page and a description of the POSIX API in the
