configFileLoad(3)             Programmer's Manual            configFileLoad(3)

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
