34DESCRIPTION
35</b><br>
36<P>
37This function compiles a regular expression into an internal form. It is the
38same as <b>pcre[16]_compile()</b>, except for the addition of the
39<i>errorcodeptr</i> argument. The arguments are:
40<pre>
41  <i>pattern</i>       A zero-terminated string containing the
42                  regular expression to be compiled
43  <i>options</i>       Zero or more option bits
44  <i>errorcodeptr</i>  Where to put an error code
45  <i>errptr</i>        Where to put an error message
46  <i>erroffset</i>     Offset in pattern where error was found
47  <i>tableptr</i>      Pointer to character tables, or NULL to
48                  use the built-in default
49</pre>
50The option bits are:
51<pre>
52  PCRE_ANCHORED           Force pattern anchoring
53  PCRE_AUTO_CALLOUT       Compile automatic callouts
54  PCRE_BSR_ANYCRLF        \R matches only CR, LF, or CRLF
55  PCRE_BSR_UNICODE        \R matches all Unicode line endings
56  PCRE_CASELESS           Do caseless matching
57  PCRE_DOLLAR_ENDONLY     $ not to match newline at end
58  PCRE_DOTALL             . matches anything including NL
59  PCRE_DUPNAMES           Allow duplicate names for subpatterns
60  PCRE_EXTENDED           Ignore white space and # comments
61  PCRE_EXTRA              PCRE extra features
62                            (not much use currently)
63  PCRE_FIRSTLINE          Force matching to be before newline
64  PCRE_JAVASCRIPT_COMPAT  JavaScript compatibility
65  PCRE_MULTILINE          ^ and $ match newlines within data
66  PCRE_NEWLINE_ANY        Recognize any Unicode newline sequence
67  PCRE_NEWLINE_ANYCRLF    Recognize CR, LF, and CRLF as newline
68                            sequences
69  PCRE_NEWLINE_CR         Set CR as the newline sequence
70  PCRE_NEWLINE_CRLF       Set CRLF as the newline sequence
71  PCRE_NEWLINE_LF         Set LF as the newline sequence
72  PCRE_NO_AUTO_CAPTURE    Disable numbered capturing paren-
73                            theses (named ones available)
74  PCRE_NO_UTF16_CHECK     Do not check the pattern for UTF-16
75                            validity (only relevant if
76                            PCRE_UTF16 is set)
77  PCRE_NO_UTF8_CHECK      Do not check the pattern for UTF-8
78                            validity (only relevant if
79                            PCRE_UTF8 is set)
80  PCRE_UCP                Use Unicode properties for \d, \w, etc.
81  PCRE_UNGREEDY           Invert greediness of quantifiers
82  PCRE_UTF16              Run <b>pcre16_compile()</b> in UTF-16 mode
83  PCRE_UTF8               Run <b>pcre_compile()</b> in UTF-8 mode
84</pre>
85PCRE must be built with UTF support in order to use PCRE_UTF8/16 and
86PCRE_NO_UTF8/16_CHECK, and with UCP support if PCRE_UCP is used.

89The yield of the function is a pointer to a private data structure that
90contains the compiled pattern, or NULL if an error was detected. Note that
91compiling regular expressions with one version of PCRE for use with a different
92version is not guaranteed to work and may cause crashes.
