DESCRIPTION

18       This routine will find an entry in a nested  value  option  or  config‐
19       urable.   If  "valueName"  is  NULL,  then the first entry is returned.
20       Otherwise, the first entry with a name that exactly matches  the  argu‐
21       ment will be returned.  If there is no matching value, NULL is returned
22       and errno is set to ENOENT. If the provided option value is not a hier‐
23       archical value, NULL is also returned and errno is set to EINVAL.
