30 This function compiles a regular expression into an internal form. It is the
31 same as <b>pcre_compile2()</b>, except for the absence of the <i>errorcodeptr</i>
32 argument. Its arguments are:
33 <pre>
34 <i>pattern</i> A zero-terminated string containing the
35 regular expression to be compiled
36 <i>options</i> Zero or more option bits
37 <i>errptr</i> Where to put an error message
38 <i>erroffset</i> Offset in pattern where error was found
39 <i>tableptr</i> Pointer to character tables, or NULL to
40 use the built-in default
41 </pre>
42 The option bits are:
43 <pre>
44 PCRE_ANCHORED Force pattern anchoring
45 PCRE_AUTO_CALLOUT Compile automatic callouts
46 PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF
47 PCRE_BSR_UNICODE \R matches all Unicode line endings
48 PCRE_CASELESS Do caseless matching
49 PCRE_DOLLAR_ENDONLY $ not to match newline at end
50 PCRE_DOTALL . matches anything including NL
51 PCRE_DUPNAMES Allow duplicate names for subpatterns
52 PCRE_EXTENDED Ignore whitespace and # comments
53 PCRE_EXTRA PCRE extra features
54 (not much use currently)
55 PCRE_FIRSTLINE Force matching to be before newline
56 PCRE_MULTILINE ^ and $ match newlines within data
57 PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
58 PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline sequences
59 PCRE_NEWLINE_CR Set CR as the newline sequence
60 PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
61 PCRE_NEWLINE_LF Set LF as the newline sequence
62 PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
63 theses (named ones available)
64 PCRE_UNGREEDY Invert greediness of quantifiers
65 PCRE_UTF8 Run in UTF-8 mode
66 PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
67 validity (only relevant if
68 PCRE_UTF8 is set)
69 </pre>
70 PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and
72 </P>
73 <P>
74 The yield of the function is a pointer to a private data structure that
75 contains the compiled pattern, or NULL if an error was detected. Note that
76 compiling regular expressions with one version of PCRE for use with a different
77 version is not guaranteed to work and may cause crashes.
