DESCRIPTION
|
|
</b><br>
|
|
<P>
|
|
This function compiles a regular expression into an internal form. It is the
|
|
same as <b>pcre[16|32]_compile()</b>, except for the addition of the
|
|
<i>errorcodeptr</i> argument. The arguments are:
|
|
<pre>
|
|
<i>pattern</i> A zero-terminated string containing the
|
|
regular expression to be compiled
|
|
<i>options</i> Zero or more option bits
|
|
<i>errorcodeptr</i> Where to put an error code
|
|
<i>errptr</i> Where to put an error message
|
|
<i>erroffset</i> Offset in pattern where error was found
|
|
<i>tableptr</i> Pointer to character tables, or NULL to
|
|
use the built-in default
|
|
</pre>
|
|
The option bits are:
|
|
<pre>
|
|
PCRE_ANCHORED Force pattern anchoring
|
|
PCRE_AUTO_CALLOUT Compile automatic callouts
|
|
PCRE_BSR_ANYCRLF \R matches only CR, LF, or CRLF
|
|
PCRE_BSR_UNICODE \R matches all Unicode line endings
|
|
PCRE_CASELESS Do caseless matching
|
|
PCRE_DOLLAR_ENDONLY $ not to match newline at end
|
|
PCRE_DOTALL . matches anything including NL
|
|
PCRE_DUPNAMES Allow duplicate names for subpatterns
|
|
PCRE_EXTENDED Ignore white space and # comments
|
|
PCRE_EXTRA PCRE extra features
|
|
(not much use currently)
|
|
PCRE_FIRSTLINE Force matching to be before newline
|
|
PCRE_JAVASCRIPT_COMPAT JavaScript compatibility
|
|
PCRE_MULTILINE ^ and $ match newlines within data
|
|
PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
|
|
PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline
|
|
sequences
|
|
PCRE_NEWLINE_CR Set CR as the newline sequence
|
|
PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
|
|
PCRE_NEWLINE_LF Set LF as the newline sequence
|
|
PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
|
|
theses (named ones available)
|
|
PCRE_NO_UTF16_CHECK Do not check the pattern for UTF-16
|
|
validity (only relevant if
|
|
PCRE_UTF16 is set)
|
|
PCRE_NO_UTF32_CHECK Do not check the pattern for UTF-32
|
|
validity (only relevant if
|
|
PCRE_UTF32 is set)
|
|
PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
|
|
validity (only relevant if
|
|
PCRE_UTF8 is set)
|
|
PCRE_UCP Use Unicode properties for \d, \w, etc.
|
|
PCRE_UNGREEDY Invert greediness of quantifiers
|
|
PCRE_UTF16 Run <b>pcre16_compile()</b> in UTF-16 mode
|
|
PCRE_UTF32 Run <b>pcre32_compile()</b> in UTF-32 mode
|
|
PCRE_UTF8 Run <b>pcre_compile()</b> in UTF-8 mode
|
|
</pre>
|
|
PCRE must be built with UTF support in order to use PCRE_UTF8/16/32 and
|
|
PCRE_NO_UTF8/16/32_CHECK, and with UCP support if PCRE_UCP is used.
|
|
</P>

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