Question

Contents

What is wrong with you? I don't understand I've never tampered with wingdi.h

If it doesn't work, I'll abandon gcc and c language. I'll make my own compiler and language. If you criticize me, I'd like to create a service like stackoverflow as a countermeasure.

What I did

wingdi.h Here's looking at you, kid

typedef {
  unsigned int  UINT,
  int           WORD,
  long long     DWORD,
  unsigned char UCHAR,
  byte          BYTE,
  void**        POINT,
}

Environment

windows 10 (64bits)

gcc (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0

// 他のだっとめんどくさいから許してね？w

#include <stdio.h>

#include <windows.h>

void wingdi__display__write(int win_hei, int win_wid, int display_map);

void main(void){
  wingdi__display__write(1000,1000,0);
}

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
  return 0;
}


//wingdi
void wingdi__display__write(int win_hei, int win_wid, int display_map)
{
  HDC  object    =    NULL,  hdc    =    NULL;
  HWND handle    =    NULL;
  HBRUSH brush   =    NULL;

  hdc            =    GetDC(handle);  
  brush = CreateSolidBrush(RGB(0, 0, 0));
  SelectObject(object, brush);

  BitBlt(hdc, 0, 0, win_wid, win_hei, object, 0, 0, SRCCOPY);
}

C does not support a "block typedef " as you have shown; each typedef must appear separately as follows:

typedef unsigned int  UINT;
typedef int           WORD;
typedef long long     DWORD;
typedef unsigned char UCHAR;
typedef uint8_t       BYTE;
typedef void**        POINT;

And BTW, it is considered bad practice to hide a pointer type behind a typedef , so your POINT should be eliminated.
