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* pzFile);


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().

       pzFile 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 empty.

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

       ENOMEM - not enough memory to allocate the needed structures.
