Relative paths do work. You have to use apr_procattr_dir_set. It is relative 
to the calling process cwd.
I need to set cwd directory to be the directory location of the calling 
process.
e.g.
If the parent process is /openload/bin/openload.exe.
I need to set the directory location to "/openload/bin".
In the apr how do you get the directory of the main process?
    status = apr_procattr_dir_set(attr,directory_location);
