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. Its
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 available codes are:
<pre>
  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_UTF8          Availability of UTF-8 support (1=yes 0=no)
  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.
