DESCRIPTION
</b><br>
<P>
This function makes it possible for a client program to find out which optional
features are available in the version of the PCRE library it is using. The
arguments are as follows:
<pre>
<i>what</i> A code specifying what information is required
<i>where</i> Points to where to put the data
</pre>
The <i>where</i> argument must point to an integer variable, except for
PCRE_CONFIG_MATCH_LIMIT and PCRE_CONFIG_MATCH_LIMIT_RECURSION, when it must
point to an unsigned long integer. The available codes are:
<pre>
PCRE_CONFIG_JIT Availability of just-in-time compiler
support (1=yes 0=no)
PCRE_CONFIG_JITTARGET String containing information about the
target architecture for the JIT compiler,
or NULL if there is no JIT support
PCRE_CONFIG_LINK_SIZE Internal link size: 2, 3, or 4
PCRE_CONFIG_MATCH_LIMIT Internal resource limit
PCRE_CONFIG_MATCH_LIMIT_RECURSION
Internal recursion depth limit
PCRE_CONFIG_NEWLINE Value of the default newline sequence:
13 (0x000d) for CR
10 (0x000a) for LF
3338 (0x0d0a) for CRLF
-2 for ANYCRLF
-1 for ANY
PCRE_CONFIG_BSR Indicates what \R matches by default:
0 all Unicode line endings
1 CR, LF, or CRLF only
PCRE_CONFIG_POSIX_MALLOC_THRESHOLD
Threshold of return slots, above which
<b>malloc()</b> is used by the POSIX API
PCRE_CONFIG_STACKRECURSE Recursion implementation (1=stack 0=heap)
PCRE_CONFIG_UTF16 Availability of UTF-16 support (1=yes
0=no); option for <b>pcre16_config()</b>
PCRE_CONFIG_UTF32 Availability of UTF-32 support (1=yes
0=no); option for <b>pcre32_config()</b>
PCRE_CONFIG_UTF8 Availability of UTF-8 support (1=yes 0=no);
option for <b>pcre_config()</b>
PCRE_CONFIG_UNICODE_PROPERTIES
Availability of Unicode property support
(1=yes 0=no)
</pre>
The function yields 0 on success or PCRE_ERROR_BADOPTION otherwise. That error
is also given if PCRE_CONFIG_UTF16 or PCRE_CONFIG_UTF32 is passed to
<b>pcre_config()</b>, if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF32 is passed to
<b>pcre16_config()</b>, or if PCRE_CONFIG_UTF8 or PCRE_CONFIG_UTF16 is passed to
<b>pcre32_config()</b>.
