 * PURPOSE
 *
 *  This is an implementation of a common MS API call. This implementation

 *  For example; unixODBC has its own so those using unixODBC should NOT be
 *  using this implementation because unixODBC;
 *  - provides caching of ODBC config data 
 *  - provides consistent interpretation of ODBC config data (i.e, location)
 *
 * ARGS
 *
 *  see ODBC documentation
 *                      
 * RETURNS
 *
 *  see ODBC documentation
 *
 * NOTES:
 *
 *  - the spec is not entirely implemented... consider this a lite version
 *  - rules for determining the location of ODBC config may be different then what you 
 *    expect see tdoGetIniFileName().
