问题描述

无法弄清楚为什么这段代码无效。没有提到我需要设置cbSize属性。我记得在另一个函数上看到它需要，我猜这是Windows API中的常见做法。

Couldn't figure out why this code wasn't working. The documentation didn't mention that I needed to set the cbSize property. I remember seeing it needed on another function, and I'm guessing that's common practice in the Windows API.

#include <Windows.h>
#include <iostream>
int main()
{
	CONSOLE_FONT_INFOEX cfo;
	cfo.cbSize = sizeof(CONSOLE_FONT_INFOEX); //Forgot this line. Here's the bug.
	if(!::GetCurrentConsoleFontEx(GetStdHandle(STD_OUTPUT_HANDLE), FALSE, &cfo)) {
		std::wcout << GetLastError() << std::endl;
		return -1;
	}
	std::wcout << cfo.FaceName << std::endl;
	return 0;
}

CONSOLE_FONT_INFOEX结构接收到请求的字体信息和结构包含cbsize，这个结构的大小，以字节为单位。我建议你可以参考这个

链接，或等待。$

The CONSOLE_FONT_INFOEX structure receives the requested font information and the structure contains cbsize, which is the size of this structure, in bytes. I suggest you could refer to thislink, or wait for the feedback.
