请问TC中怎样允许键盘鼠标同时操作界面
#define __MOUSE_H__
/*****************************************************************************************
概念定义及程序说明
程序名称：鼠标I/O程序
日期：7/28/98
说明：本程序提供鼠标的基本输入输出功能。目前已经使用到的函数加有说明。
程序使用的是INT 33H 鼠标中断。
其他：包含mouse.h和mouse.cpp两个文件
*****************************************************************************************/
intreset_mouse(void);//reset mouse. return -1 if sucess and return others if mouse hard/soft-ware do not exist
voidshow_mouse(void);//打开鼠标，1号调用，图形方式下出现的是缺省的“箭头”
voidhide_mouse(void);//隐藏鼠标，2号调用
void BeginLongPeriodHideMouse();
void EndLongPeriodHideMouse();
intMonitorMouse(int *AX,int *BX,int *CX,int *DX);//检测鼠标，3号调用，结果返回的是AX,BX,CX,DX寄存器的值
//int push_button(void);
//void release_button(int button, int hor, int ver);
//void put_mouse(int mousex, int mousey);
//void max_hor(int min, int max);
//void max_ver(int min, int max);
//void max_ver_hor(int left, int top, int right, int bottom);
//void setcursor(int XHotSpot, int YHotSpot, int shape_tables, int seg_shape_tables);
//void mouse_move_ratio(int ratio);
//void hidden_area(int left, int top, int right, int bottom);
//void SetMouseEventHandle(unsigned char mask, int offset, int segment);
//void GetMouseRet(int *AX,int *BX,int *CX,int *DX);//3号调用的返回值
