43 This function compiles a regular expression into an internal form. It is the
44 same as <b>pcre[16|32]_compile()</b>, except for the addition of the
45 <i>errorcodeptr</i> argument. The arguments are:
46 <pre>
47 <i>pattern</i> A zero-terminated string containing the
48 regular expression to be compiled
49 <i>options</i> Zero or more option bits
50 <i>errorcodeptr</i> Where to put an error code
51 <i>errptr</i> Where to put an error message
52 <i>erroffset</i> Offset in pattern where error was found
53 <i>tableptr</i> Pointer to character tables, or NULL to
54 use the built-in default
55 </pre>
56 The option bits are:
57 <pre>
58 PCRE_ANCHORED Force pattern anchoring
59 PCRE_AUTO_CALLOUT Compile automatic callouts
60 PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF
61 PCRE_BSR_UNICODE \R matches all Unicode line endings
62 PCRE_CASELESS Do caseless matching
63 PCRE_DOLLAR_ENDONLY $ not to match newline at end
64 PCRE_DOTALL . matches anything including NL
65 PCRE_DUPNAMES Allow duplicate names for subpatterns
66 PCRE_EXTENDED Ignore white space and # comments
67 PCRE_EXTRA PCRE extra features
68 (not much use currently)
69 PCRE_FIRSTLINE Force matching to be before newline
70 PCRE_JAVASCRIPT_COMPAT JavaScript compatibility
71 PCRE_MULTILINE ^ and $ match newlines within data
72 PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
73 PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline
74 sequences
75 PCRE_NEWLINE_CR Set CR as the newline sequence
76 PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
77 PCRE_NEWLINE_LF Set LF as the newline sequence
78 PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
79 theses (named ones available)
80 PCRE_NO_UTF16_CHECK Do not check the pattern for UTF-16
81 validity (only relevant if
82 PCRE_UTF16 is set)
83 PCRE_NO_UTF32_CHECK Do not check the pattern for UTF-32
84 validity (only relevant if
85 PCRE_UTF32 is set)
86 PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
87 validity (only relevant if
88 PCRE_UTF8 is set)
89 PCRE_UCP Use Unicode properties for \d, \w, etc.
90 PCRE_UNGREEDY Invert greediness of quantifiers
91 PCRE_UTF16 Run <b>pcre16_compile()</b> in UTF-16 mode
92 PCRE_UTF32 Run <b>pcre32_compile()</b> in UTF-32 mode
93 PCRE_UTF8 Run <b>pcre_compile()</b> in UTF-8 mode
94 </pre>
95 PCRE must be built with UTF support in order to use PCRE_UTF8/16/32 and
96 PCRE_NO_UTF8/16/32_CHECK, and with UCP support if PCRE_UCP is used.

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