 This convenience function finds the number of a named substring capturing
-parenthesis in a compiled pattern. Its arguments are:
+parenthesis in a compiled pattern, provided that it is a unique name. The 
+function arguments are:

   \fIcode\fP    Compiled regular expression
   \fIname\fP    Name whose number is required

 The yield of the function is the number of the parenthesis if the name is
-found, or PCRE2_ERROR_NOSUBSTRING otherwise. When duplicate names are allowed
-(PCRE2_DUPNAMES is set), it is not defined which of the numbers is returned.
