This function compiles a regular expression into an internal form. It is the
|
||
|
|
same as <b>pcre[16|32]_compile2()</b>, except for the absence of the
|
||
|
|
<i>errorcodeptr</i> argument. Its 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>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>
|
||
|

PCRE_UTF32 Run in <b>pcre32_compile()</b> UTF-32 mode
|
||
|
|
PCRE_UTF8 Run in <b>pcre_compile()</b> UTF-8 mode

|
|
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.

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.
