The Inifile instrument driver contains functions to:\n\\n\   - create and dispose an object which can contain an in-memory\n\     list of tag/value pairs.\n\   - sort the in-memory list of tag/value pairs\n\   - read a list of tag/value pairs from a file\n\   - write the in-memory list of tag/value pairs to a file\n\\n\This example opens an existing *.ini file and allows you to display,\n\add, and remove sections and items from the inifile.\n\\n\Note: The Inifile instrument driver treats empty tag items as if they\n\are not defined.  For example, if the Ini file contains,\n\    [Ports]\n\    COM1 = 9600\n\    COM2 =\n\the COM2 tag will not be read in."/*--------------------------------------------------------------------------*//* Includes                                                                 *//*--------------------------------------------------------------------------*//* #include <windows.h> For call to SDK function GetSystemDirectory() if used */#include <utility.h>#include <userint.h>#include "inifile.h"#include "ini.h"/*--------------------------------------------------------------------------*//* Defines                                                                  *//*--------------------------------------------------------------------------*/#define MAX_NAME_SIZE 256/*--------------------------------------------------------------------------*//* Variables                                                                *//*--------------------------------------------------------------------------*/static int panelHandle   = 0;static int changesMade   = 0;static IniText myInifile = 0;static char fileName[MAX_PATHNAME_LEN];/*--------------------------------------------------------------------------*//* Prototypes                                                               *//*--------------------------------------------------------------------------*/int UpdateUIR(void);
