Test of CreateConsoleScreenBuffer and SetConsoleActiveScreenBuffer (Doesn't work on winpty)

CreateScrBuf.c

#include <windows.h>
#include <stdio.h>
#include <conio.h>
#include <io.h>

int main()
{
	HANDLE hScr, hConOut;
	DWORD written;
	int c;
	char buf[10];

	hConOut = GetStdHandle(STD_OUTPUT_HANDLE);
	hScr = CreateConsoleScreenBuffer(
			GENERIC_READ | GENERIC_WRITE,
			FILE_SHARE_READ | FILE_SHARE_WRITE,
			NULL, CONSOLE_TEXTMODE_BUFFER, NULL);

	SetConsoleActiveScreenBuffer(hScr);

	while (1) {
		c = getch();
		sprintf(buf, "%02x ", c);
		WriteFile(hScr, buf, strlen(buf), &written, NULL);
		if (c == 0x1b || c == 0x03)
			break;
	}

	SetConsoleActiveScreenBuffer(hConOut);
	CloseHandle(hScr);

	return 0;
