c - 无效的初始化程序？

Question

01 #include <stdio.h>
02 #include <stdlib.h>
03 #include <windows.h>
04 
05 HANDLE StdHandle;
06 
07 int  RGBI (int Red, int Green, int Blue, int Intensified);
08 int Set_Color (int RGB_Fore, int RGB_Back);
09 
10 int main (void)
11 {
12   StdHandle = GetStdHandle(STD_OUTPUT_HANDLE);
13   Set_Color(RGBI(0,1,0,1), RGBI(0,0,1,1));
14   char Str [8] = "Great.\n";
15   printf("%s", Str);
16   system("pause>nul");
17   CONSOLE_FONT_INFO FONT;
18   GetCurrentConsoleFont(StdHandle, FALSE, &FONT);
19   COORD Fontsize = GetConsoleFontSize(StdHandle, FONT.nFont);
20   return 0;
21 }
22 
23 int RGBI (int Red, int Green, int Blue, int Intensified)
24 {
25   return (Intensified*8 + Red*4 + Green*2 + Blue);
26 }
27 
28 int Set_Color (int RGB_Fore, int RGB_Back)
29 {
30   SetConsoleTextAttribute(StdHandle, RGB_Fore + RGB_Back*16);
31   return 0;
32 }

为什么？我应该更新 windows.h 吗？

哪里可以下载最新版本的windows.h？

谢谢。

我相信您需要定义最低 Windows 版本，因此请在 #include <windows.h> 之前添加此版本

#define _WIN32_WINNT 0x500 

MSDN says:

To compile an application that uses this function, define _WIN32_WINNT as 0x0500 or later. For more information, see Using the Windows Headers.
