DESCRIPTION

17       This routine will load a named configuration file and parse the text as
18       a hierarchically valued option.  The option descriptor created from  an
19       option  definition  file  is not used via this interface.  The returned
20       value  is  "named"  with  the  input  file  name   and   is   of   type
21       "OPARG_TYPE_HIERARCHY".   It  may be used in calls to optionGetValue(),
22       optionNextValue() and optionUnloadNested().

ERRORS

32       If the file cannot be loaded or processed, NULL is returned  and  errno
33       is  set.   It  may  be set by a call to either open(2) mmap(2) or other
34       file system calls, or it may be:
