It has also been aligned with the -** Linux version. See CVS for revisions. This will work for Win 9x onwards. -**************************************************************************** -** -** Notes on Windows interface to driver -** ************************************ -** -** Under Windows 9x and NT, Use1401 uses DeviceIoControl to get access to -** the 1401 driver. This has parameters for the device handle, the function -** code, an input pointer and byte count, an output pointer and byte count -** and a pointer to a unsigned int to hold the output byte count. Note that input -** and output are from the point-of-view of the driver, so the output stuff -** is used to read values from the 1401, not send to the 1401. The use of -** these parameters varies with the function in use and the operating -** system; there are five separate DIOC calls SendString, GetString and -** SetTransferArea all have their own specialised calls, the rest use the -** Status1401 or Control1401 functions. -** -** There are two basic styles of DIOC call used, one for Win9x VxD drivers -** and one for NT Kernel-mode and WDM drivers (see below for tables showing -** the different parameters used. The array bUseNTDIOC[] selects between -** these two calling styles. -** -** Function codes -** In Win3.x, simple function codes from 0 to 40 were used, shifted left 8 -** bits with a sub-function code in the lower 8 bits. These were also used -** in the Windows 95 driver, though we had to add 1 to the code value to -** avoid problems (Open from CreateFile is zero), and the sub-function code -** is now unused. We found that this gave some problems with Windows 98 -** as the function code values are reserved by microsoft, so we switched to -** using the NT function codes instead. The NT codes are generated using the -** CTL_CODE macro, essentially this gives 0x80012000 | (func << 2), where -** func is the original 0 to 34 value. The driver will handle both types of -** code and Use1432 only uses the NT codes if it knows the driver is new -** enough. The array bUseNTCodes[] holds flags on the type of codes required. -** GPS/TDB Dec 2010: we removed the bUseNTCodes array as this is always true -** as we no longer support ancient versions. -** -** The CreateFile and CloseFile function calls are also handled -** by DIOC, using the special function codes 0 and -1 respectively. -** -** Input pointer and buffer size -** These are intended for data sent to the device driver. In nearly all cases -** they are unused in calls to the Win95 driver, the NT driver uses them -** for all information sent to the driver. The table below shows the pointer -** and byte count used for the various calls: -** -** Win 95 Win NT -** SendString NULL, 0 pStr, nStr -** GetString NULL, 0 NULL, 0 -** SetTransferArea pBuf, nBuf (unused?) pDesc, nDesc -** GetTransfer NULL, 0 NULL, 0 -** Status1401 NULL, 0 NULL, 0 -** Control1401 NULL, 0 pBlk, nBlk -** -** pStr and nStr are pointers to a char buffer and the buffer length for -** string I/O, note that these are temporary buffers owned by the DLL, not -** application memory, pBuf and nBuf are the transfer area buffer (I think -** these are unused), pDesc and nDesc are the TRANSFERDESC structure, pBlk -** and nBlk are the TCSBLOCK structure. -** -** -** Output pointer and buffer size -** These are intended for data read from the device driver. These are used -** for almost all information sent to the Win95 driver, the NT driver uses -** them for information read from the driver, chiefly the error code. The -** table below shows the pointer and byte count used for the various calls: -** -** Win 95 Win NT -** SendString pStr, nStr pPar, nPar -** GetString pStr, nStr+2 pStr, nStr+2 -** SetTransferArea pDesc, nDesc pPar, nPar -** GetTransfer pGet, nGet pGet, nGet -** Status1401 pBlk, nBlk pPar, nPar -** Control1401 pBlk, nBlk pPar, nPar -** -** pStr and nStr are pointers to a char buffer and the buffer length for -** string I/O, the +2 for GetString refers to two spare bytes at the start -** used to hold the string length and returning an error code for NT. Note -** again that these are (and must be) DLL-owned temporary buffers. pPar -** and nPar are a PARAM structure used in NT (it holds an error code and a -** TCSBLOCK structure). pDesc and nDesc are the VXTRANSFERDESC structure, -** pBlk and nBlk are the TCSBLOCK structure. pGet and nGet indicate the -** TGET_TX_BLOCK structure used for GetTransfer. -** -** -** The output byte count -** Both drivers return the output buffer size here, regardless of the actual -** bytes output. This is used to check that we did get through to the driver. -** -** Multiple 1401s -** ************** -** -** We have code that tries to support the use of multiple 1401s, but there -** are problems: The lDriverVersion and lDriverType variables are global, not -** per-1401 (a particular problem as the U14 functions that use them don't -** have a hand parameter). In addition, the mechansim for finding a free -** 1401 depends upon the 1401 device driver open operation failing if it's -** already in use, which doesn't always happen, particularly with the VxDs. -** The code in TryToOpen tries to fix this by relying on TYPEOF1401 to detect -** the 1401-in-use state - the VxDs contain special code to help this. This is -** working OK but multiple 1401 support works better with the Win2000 drivers. -** -** USB driver -** ********** -** -** The USB driver, which runs on both Win98 and NT2000, uses the NT-style -** calling convention, both for the DIOC codes and the DIOC parameters. The -** TryToOpen function has been altered to look for an NT driver first in -** the appropriate circumstances, and to set the driver DIOC flags up in -** the correct state. -** -** Adding a new 1401 type - now almost nothing to do -** ************************************************* -** -** The 1401 types are defined by a set of U14TYPExxxx codes in USE1401.H. -** You should add a new one of these to keep things tidy for applications. -** -** DRIVERET_MAX (below) specifies the maximum allowed type code from the -** 1401 driver; I have set this high to accommodate as yet undesigned 1401 -** types. Similarly, as long as the command file names follow the ARM, -** ARN, ARO sequence, these are calculated by the ExtForType function, so -** you don't need to do anything here either. -** -** Version number -** ************** -** The new U14InitLib() function returns 0 if the OS is incapable of use, -** otherwise is returns the version of the USE1401 library. This is done -** in three parts: Major(31-24).Minor(23-16).Revision.(15-0) (brackets are -** the bits used). The Major number starts at 2 for the first revision with -** the U14InitLib() function. Changes to the Major version means that we -** have broken backwards compatibility. Minor number changes mean that we -** have added new functionality that does not break backwards compatibility. -** we starts at 0. Revision changes mean we have fixed something. Each index -** returns to 0 when a higher one changes. -*/ -#define U14LIB_MAJOR 4 -#define U14LIB_MINOR 0 -#define U14LIB_REVISION 0 -#define U14LIB_VERSION ((U14LIB_MAJOR<<24) | (U14LIB_MINOR<<16) | U14LIB_REVISION) - -#include <stdlib.h> -#include <string.h> -#include <stdio.h> - -#include "USE1401.H" - -#ifdef _IS_WINDOWS_ -#include <io.h> -#include <windows.h> -#pragma warning(disable: 4100) /* Disable "Unused formal parameter" warning */ -#include <assert.h> -#include "process.h" - - -#define sprintf wsprintf -#define PATHSEP '\\' -#define PATHSEPSTR "\\" -#define DEFCMDPATH "\\1401\\" // default command path if all else fails -#define MINDRIVERMAJREV 1 // minimum driver revision level we need -#define __packed // does nothing in Windows - -#include "use14_ioc.h" // links to device driver stuff -#endif - -#ifdef LINUX -#include <fcntl.h> -#include <unistd.h> -#include <sys/ioctl.h> -#include <errno.h> -#include <sys/time.h> -#include <sched.h> -#include <libgen.h> -#define PATHSEP '/' -#define PATHSEPSTR "/" -#define DEFCMDPATH "/var/1401/" // default command path if all else fails -#define MINDRIVERMAJREV 2 // minimum driver revision level we need - -#include "ced_ioctl.h" // links to device driver stuff -#endif - -#define MAX1401 8 // The number of 1401s that can be supported - -/* -** These are the 1401 type codes returned by the driver, they are a slightly -** odd sequence & start for reasons of compatibility with the DOS driver. -** The maximum code value is the upper limit of 1401 device types. -*/ -#define DRIVRET_STD 4 // Codes for 1401 types matching driver values -#define DRIVRET_U1401 5 // This table does not need extending, as -#define DRIVRET_PLUS 6 // we can calculate values now. -#define DRIVRET_POWER 7 // but we need all of these values still -#define DRIVRET_MAX 26 // Maximum tolerated code - future designs - -/* -** These variables store data that will be used to generate the last -** error string.
