1. Introduction
============================================================================
NJSDK is a C Library based on NJSTAR Version 3.0. It contains all the
functions for handling Chinese input, display and printing. With NJSDK, user
can develop any Chinese applications without knowing how Chinese characters
are inputed, displayed or printed. It is as easy as writing an English
program.
NJSDK provides a Chinese interface for any C program. It reserves the bottom
line for Chinese input, and all other 24 lines (on VGA, 18 on EGA, 29 on
SVGA) are working area for the application. NJSDK starts by loading Chinese
font and dictionaries into memory, which require 200KB. If user select to
leave font on disk, then NJSDK only requires 80KB to operate. When NJSDK
exits, all used memory are released, and screen is back to text mode.
NJSDK supports all the input methods in NJSTAR v3.0, user defined methods
also supported in the same way as in NJSTAR. ALT+Function Keys are reserved
by NJSDK for switching between the Chinese input methods (as listed in next
section), and other Chinese related function.
Mouse operations are directly supported by NJSDK, application program can
get mouse position by calling the NJSDK mouse functions.
Screen Saver and AutoSave facilities have been built in NJSDK. Active
interval can be set by a configuration program NJSDKCFG.EXE.
2. License Information
============================================================================
With the full payment for NJSDK, the developer are granted a distribution
license which permits the distribution of all NJSTAR dictionaries, drivers
and fonts (total 30 files) with their application without any further
royalty payment. Distribution of any Executable file (*.EXE) of NJSTAR is
strictly prohibited. Each licensed copy has an unique serial number, this
protects any illegal use of NJSDK by other un-licensed users. Licensed user
are entitled a free upgrade to next version of NJSDK when it becomes
available. Please contact the author for current price. Please contact the
author if you or your company have any special requirements or cooperations.

defects in material and workmanship, assuming normal use, for a period
of 30 days from the date of purchase.
B) The Author of NJSDK warrants that the program will perform in
substantial compliance with the documentation supplied within this
document. If a significant defect in the product is found, the
Purchaser may return the product for a refund. In no event will such
a refund exceed the purchase price of the product.
C) Use of this product for any period of time constitutes your acceptance

INABILITY TO USE THIS PRODUCT EVEN IF THE AUTHOR HAS BEEN ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES.
3. List of files in NJSDK package
============================================================================
NJSDK.LIB The NJSDK C subroutine library (MSC 7.0 Large model)
NJSDK.H The header file for NJSDK
KEYS.H The header file for key and mouse button definitions
******.C Example programs
CC.BAT Batch file used to compile program, eg. CC hello
NJSDK.DOC NJSDK user manual in MS-Word 2.0 for Win. Format
NJSDK.TXT Text version of NJSDK.DOC
NJSDK.INI Tell NJSDK where are the NJSTAR dictionaries & font
NJSDK.CFG NJSDK configuration file
NJSDKCFG.EXE The application configuration program
SUPER.VGA The super VGA definition file (required by NJSDKCFG)
Following files from NJSTAR are needed for program based on NJSDK to run.
Those files can be distributed with user's .EXE file only after a proper
distribution license has been purchased.
CCLIB.16 16x16 Simplified Chinese bitmap
CCLIB.24 24x24 Simplified Chinese bitmap (With Reg. ver)
CCLIBF.16 16x16 un-Simplified Chinese bitmap
CCLIBF.24 24x24 un-Simplified Chinese bitmap (With Reg. ver)
ASCII.16 16x8 Ascii bitmap
ASCII.24 24x12 Ascii bitmap
NANJIPY.DIC NJSTAR PinYin dictionary
NANJILX.DIC NJSTAR Lianxiang dictionary
NJINPUT*.DIC External character input methods dictionary
NJCIZU*.DIC External word input methods dictionary
TOLERATE.DIC PinYin Tolerance lists (text file)
********.DRV Printer drivers
If NJSTAR is installed on C:\NJSTAR, a file NJSDK.INI can be created in
the same directory as user's application. It should contains two lines:
NJDIC=C:\NJSTAR
NJZK=C:\NJSTAR
NJSDK will try to locate the font and dictionaries in the same directory as
users EXE file. If not found, NJSDK will try those as defined in NJSDK.INI.
user can also set two DOS environment variables in AUTOEXEC.BAT to specify
the location of fonts and dictionaries (override NJSDK.INI).
SET NJZK=C:\NJSTAR
SET NJDIC=C:\NJSTAR
In this way, only one set of font and dictionaries are needed in one
computer, all the NJSDK applications and NJSTAR can access the same font
and dictionaries.
