+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 PCRE2 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 information
+</pre>
+If <i>where</i> is NULL, the function returns the amount of memory needed for
+the requested information. When the information is a string, the value is in
+code units; for other types of data it is in bytes.
+</P>
+<P>
+If <b>where</b> is not NULL, for PCRE2_CONFIG_JITTARGET,
+PCRE2_CONFIG_UNICODE_VERSION, and PCRE2_CONFIG_VERSION it must point to a
+buffer that is large enough to hold the string. For all other codes it must
+point to a uint32_t integer variable. The available codes are:
+<pre>
+ PCRE2_CONFIG_BSR Indicates what \R matches by default:
+ PCRE2_BSR_UNICODE
+ PCRE2_BSR_ANYCRLF
+ PCRE2_CONFIG_COMPILED_WIDTHS Which of 8/16/32 support was compiled
+ PCRE2_CONFIG_DEPTHLIMIT Default backtracking depth limit
+ PCRE2_CONFIG_HEAPLIMIT Default heap memory limit
+ PCRE2_CONFIG_JIT Availability of just-in-time compiler support (1=yes 0=no)
+ PCRE2_CONFIG_JITTARGET Information (a string) about the target architecture for the JIT compiler
+ PCRE2_CONFIG_LINKSIZE Configured internal link size (2, 3, 4)
+ PCRE2_CONFIG_MATCHLIMIT Default internal resource limit
+ PCRE2_CONFIG_NEVER_BACKSLASH_C Whether or not \C is disabled
+ PCRE2_CONFIG_NEWLINE Code for the default newline sequence:
+ PCRE2_NEWLINE_CR
+ PCRE2_NEWLINE_LF
+ PCRE2_NEWLINE_CRLF
+ PCRE2_NEWLINE_ANY
+ PCRE2_NEWLINE_ANYCRLF
+ PCRE2_NEWLINE_NUL
+ PCRE2_CONFIG_PARENSLIMIT Default parentheses nesting limit
+ PCRE2_CONFIG_RECURSIONLIMIT Obsolete: use PCRE2_CONFIG_DEPTHLIMIT
+ PCRE2_CONFIG_STACKRECURSE Obsolete: always returns 0
+ PCRE2_CONFIG_UNICODE Availability of Unicode support (1=yes 0=no)
+ PCRE2_CONFIG_UNICODE_VERSION The Unicode version (a string)
+ PCRE2_CONFIG_VERSION The PCRE2 version (a string)
+</pre>
+The function yields a non-negative value on success or the negative value
+PCRE2_ERROR_BADOPTION otherwise. This is also the result for the
+PCRE2_CONFIG_JITTARGET code if JIT support is not available. When a string is
+requested, the function returns the number of code units used, including the
+terminating zero.
