! 30: <P>
! 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.

! 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>
