   43 This is a convenience function for extracting a captured substring by name. The
   44 arguments are:
   45 <pre>
   46   <i>code</i>          Compiled pattern
   47   <i>subject</i>       Subject that has been successfully matched
   48   <i>ovector</i>       Offset vector that <b>pcre[16|32]_exec()</b> used
   49   <i>stringcount</i>   Value returned by <b>pcre[16|32]_exec()</b>
   50   <i>stringname</i>    Name of the required substring
   51   <i>stringptr</i>     Where to put the string pointer
   52 </pre>
   53 The memory in which the substring is placed is obtained by calling
   54 <b>pcre[16|32]_malloc()</b>. The convenience function
   55 <b>pcre[16|32]_free_substring()</b> can be used to free it when it is no longer
   56 needed. The yield of the function is the length of the extracted substring,
   57 PCRE_ERROR_NOMEMORY if sufficient memory could not be obtained, or
   58 PCRE_ERROR_NOSUBSTRING if the string name is invalid.
