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

85 There is a complete description of the PCRE native API in the
86 <a href="pcreapi.html"><b>pcreapi</b></a>
87 page and a description of the POSIX API in the
88 <a href="pcreposix.html"><b>pcreposix</b></a>
89 page.
