DESCRIPTION
       This convenience function finds the number of a named substring captur-
       ing parenthesis in a compiled pattern, provided that  it  is  a  unique
       name. The function arguments are:
         code    Compiled regular expression
         name    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 if it is not found. When duplicate
       names  are  allowed (PCRE2_DUPNAMES is set), if the name is not unique,
       PCRE2_ERROR_NOUNIQUESUBSTRING is returned. You can obtain the  list  of
       numbers with the same name by calling pcre2_substring_nametable_scan().
       There is a complete description of the PCRE2 native API in the pcre2api
       page and a description of the POSIX API in the pcre2posix page.
