嵌入式LINUX下的手写板应用软件,键盘应用

/*    IME.c  Chinese Input Method Support Routine
 *
 *    Programmed By Chen Yang ([e-mail])
 *
 *    In order to improve efficient,The program first builds
 *    an Encoded Tree of PinYin so that in the processing of
 *    the input,it doesn't need to GO BACK!!!!! On 68XX328,I
 *    think it is better if avoid this.The structure is based
 *    on the TRIER-tree,Thanks to <<Data Structure>>. Also
 *    thanks to Visual C++'s TreeControl,It is that made this
 *    a reality!!!
