NAME

       configFileLoad - parse a configuration file

SYNOPSIS

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

       const tOptionValue * configFileLoad(char const * fname);

DESCRIPTION

       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

RETURN VALUE

       An allocated, compound value structure

ERRORS

       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 itemize
