configFileLoad - parse a configuration file


   #include <your-opts.h>
   cc [...] -o outfile infile.c -lopts [...]

   const tOptionValue * configFileLoad(char const * fname);


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

   fname  the file to load


   An allocated, compound value structure


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

   ENOENT - the file was not found.

   ENOMSG - the file was empty.

   EINVAL - the file contents are invalid -- not properly formed.

   ENOMEM - not enough memory to allocate  the  needed  structures.   @end
