DESCRIPTION

16
17       This convenience function finds the number of a named substring captur‐
18       ing parenthesis in a compiled pattern, provided that  it  is  a  unique
19       name. The function arguments are:
20
21         code    Compiled regular expression
22         name    Name whose number is required
23
24       The  yield of the function is the number of the parenthesis if the name
25       is found, or PCRE2_ERROR_NOSUBSTRING if it is not found. When duplicate
26       names  are  allowed (PCRE2_DUPNAMES is set), if the name is not unique,
27       PCRE2_ERROR_NOUNIQUESUBSTRING is returned. You can obtain the  list  of
28       numbers with the same name by calling pcre2_substring_nametable_scan().

31       page and a description of the POSIX API in the pcre2posix page.
