GetCurrentConsoleFont未在作用域中声明，我做错了什么? [英] GetCurrentConsoleFont not declared in scope, what I do wrong?

问题描述

一开始我有:

#include <sstream>
#include <iostream>
#include <stdio.h>
#include <iomanip>
#include <string>
#define _WIN32_WINNT 0x500 //tells that this is win 2000 or higher, without GetConsoleWindow would not work
#include <windows.h>

using namespace std;

int main() {
  PCONSOLE_FONT_INFO lpConsoleCurrentFont;
  GetCurrentConsoleFont(GetStdHandle(STD_OUTPUT_HANDLE), false,  lpConsoleCurrentFont);
  return 0;
}

并且未记录的函数SetConsoleFont可以工作，但是GetCurrentConsoleFont编译失败，提示它未在此范围内声明.

And undocumented function SetConsoleFont works, but GetCurrentConsoleFont fails at compilation saying that it was not declared in this scope.

-更改为自持代码.

推荐答案

GetCurrentConsoleFont至少是在NT4 +上导出的，MinGW标头一定是错误的.

GetCurrentConsoleFont is exported on NT4+ at least, the MinGW headers must be wrong.

尝试在您的#include之后添加此代码:

Try adding this code after your #include's:

#ifdef __cplusplus
extern "C" {
#endif
BOOL WINAPI GetCurrentConsoleFont(HANDLE hConsoleOutput,BOOL bMaximumWindow,PCONSOLE_FONT_INFO lpConsoleCurrentFont);
#ifdef __cplusplus
}
#endif

您的代码也是错误的，应该是:

Your code is also wrong, it should be:

CONSOLE_FONT_INFO ConsoleFontInfo;
GetCurrentConsoleFont(GetStdHandle(STD_OUTPUT_HANDLE), false,  &ConsoleFontInfo);

(每次看到PSOMETYPE作为参数时，通常都会在堆栈上分配一个SOMETYPE结构，并将指向该结构的指针作为参数传递)

(Any time you see PSOMETYPE as a parameter you usually allocate a SOMETYPE struct on the stack and pass a pointer to this struct as the parameter)
