37: DESCRIPTION
38: </b><br>
39: <P>
40: This function compiles a regular expression into an internal form. It is the
1.1.1.4 ! misho 41: same as <b>pcre[16|32]_compile2()</b>, except for the absence of the
1.1.1.2 misho 42: <i>errorcodeptr</i> argument. Its arguments are:
1.1 misho 43: <pre>
44: <i>pattern</i> A zero-terminated string containing the
45: regular expression to be compiled
46: <i>options</i> Zero or more option bits
47: <i>errptr</i> Where to put an error message
48: <i>erroffset</i> Offset in pattern where error was found
49: <i>tableptr</i> Pointer to character tables, or NULL to
50: use the built-in default
51: </pre>
52: The option bits are:
53: <pre>
54: PCRE_ANCHORED Force pattern anchoring
55: PCRE_AUTO_CALLOUT Compile automatic callouts
56: PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF
57: PCRE_BSR_UNICODE \R matches all Unicode line endings
58: PCRE_CASELESS Do caseless matching
59: PCRE_DOLLAR_ENDONLY $ not to match newline at end
60: PCRE_DOTALL . matches anything including NL
61: PCRE_DUPNAMES Allow duplicate names for subpatterns
1.1.1.3 misho 62: PCRE_EXTENDED Ignore white space and # comments
1.1 misho 63: PCRE_EXTRA PCRE extra features
64: (not much use currently)
65: PCRE_FIRSTLINE Force matching to be before newline
66: PCRE_JAVASCRIPT_COMPAT JavaScript compatibility
67: PCRE_MULTILINE ^ and $ match newlines within data
68: PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
69: PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline
70: sequences
71: PCRE_NEWLINE_CR Set CR as the newline sequence
72: PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
73: PCRE_NEWLINE_LF Set LF as the newline sequence
74: PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
75: theses (named ones available)
1.1.1.2 misho 76: PCRE_NO_UTF16_CHECK Do not check the pattern for UTF-16
77: validity (only relevant if
78: PCRE_UTF16 is set)
1.1.1.4 ! misho 79: PCRE_NO_UTF32_CHECK Do not check the pattern for UTF-32
! 80: validity (only relevant if
! 81: PCRE_UTF32 is set)
1.1 misho 82: PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
83: validity (only relevant if
84: PCRE_UTF8 is set)
85: PCRE_UCP Use Unicode properties for \d, \w, etc.
86: PCRE_UNGREEDY Invert greediness of quantifiers
1.1.1.2 misho 87: PCRE_UTF16 Run in <b>pcre16_compile()</b> UTF-16 mode
1.1.1.4 ! misho 88: PCRE_UTF32 Run in <b>pcre32_compile()</b> UTF-32 mode
1.1.1.2 misho 89: PCRE_UTF8 Run in <b>pcre_compile()</b> UTF-8 mode
1.1 misho 90: </pre>
1.1.1.4 ! misho 91: PCRE must be built with UTF support in order to use PCRE_UTF8/16/32 and
! 92: PCRE_NO_UTF8/16/32_CHECK, and with UCP support if PCRE_UCP is used.

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