China DOS Union

I used the UCDOS SDK for C to make a Win window graphic interface, but there is always a UCDOS prompt bar at the bottom. I would like to ask you all which function can be used to turn it off and make the graphics fill the screen.

This is found from UCDOS. The middle ClearPromptLine(int Color) should be able to do it, set Color to your background color.

#include <stdio.h>

#include <dos.h>



int IsUcdosResident(void)

{

   union REGS regs;   regs.x.ax = 0xdb00;

   int86(0x2f,&regs,&regs);

   return regs.x.bx == 0x5450;

}void SetPromptLineColor(int Color1,int Color2,int Color3,int Color4)

{

   union REGS regs;   regs.x.ax = 0xff0f;

   regs.h.bl = 0x8b;

   regs.h.cl = Color1;

   regs.h.ch = Color2;

   regs.h.dl = Color3;

   regs.h.dh = Color4;

   int86(0x10,&regs,&regs);

}void InitPromptLine(void)

{

   union REGS regs;   regs.x.ax = 0xff07;

   int86(0x16,&regs,&regs);

}void ClearPromptLine(int Color)

{

   union REGS regs;   regs.x.ax = 0xff10;

   regs.h.bl = 0;

   regs.h.bh = Color;

   int86(0x10,&regs,&regs);

}void WritePromptMoreChar(char ch,int Color,int Count)

{

   union REGS regs;   regs.x.ax = 0xff10;

   regs.h.bl = 1;

   regs.h.bh = Color;

   regs.x.cx = Count;

   regs.h.dl = ch;

   int86(0x10,&regs,&regs);

}void WriteUcdosPromptLine(const char *msg)

{

// char msg="一二三四五六七八九十一二三四五六七八九十一二三四五六七八九十一二三四五";

 if (IsUcdosResident()) {

  char *p;

  SetPromptLineColor(0x17,0x11,0x1c,0xb1);

  InitPromptLine();

  ClearPromptLine(0x7);

  for (p=msg;*p;p++)

   WritePromptMoreChar(*p,0xb4,1);

 }

 else {

  printf("The UCDOS is not residented.\n");

 }

}

Thanks a lot, finally met an expert. For this problem, my head is almost broken. Getting the expert's guidance is like being in the spring breeze, just one word "cool". May I ask where the above code can be found, or what tool is used for decompilation? Little brother is inexperienced, hope to get more advice, and express thanks again.

Thank you very much. Recently I just happened to use it
