Header files won't work in C [closed]

问题

I'm using Dev-CPP, (but programming in C), and the header files won't work. I've gone to compiler option; directories; c inludes and checked the directory is correct, and it is. The include files are stored in C:\Dev-Cpp\include and that's where it's set to receive them.

For example:

#include <conio.h>

int main(int argc, char *argv[])
{
  textcolor(1);

  printf("Why won't header files work? \n");

  system("PAUSE");  
  return 0;
}

I've tried with several other header files, but they also don't work. I'm sure the answer is really obvious, but I'm clearly too stupid to fix this. I'm also using MinGW as the compiler, (comes standard with dev-cpp). Please help me.

textcolor() very old.(Perhaps borland c++ ?)

e.g. redefine like this

#include <Windows.h>
#include <stdio.h>
#include <conio.h>

void textcolor(unsigned short color){
    HANDLE hStdout;
    WORD wAttributes;
    CONSOLE_SCREEN_BUFFER_INFO csbi;

    hStdout = GetStdHandle(STD_OUTPUT_HANDLE);

    GetConsoleScreenBufferInfo(hStdout, &csbi);

    wAttributes = color ;
    if (color & 0x08) wAttributes |= FOREGROUND_INTENSITY ;

    SetConsoleTextAttribute(hStdout, wAttributes);
}

/*
#define FOREGROUND_BLUE      0x0001
#define FOREGROUND_GREEN     0x0002
#define FOREGROUND_RED       0x0004
#define FOREGROUND_INTENSITY 0x0008

#define BACKGROUND_BLUE      0x0010
#define BACKGROUND_GREEN     0x0020
#define BACKGROUND_RED       0x0040
#define BACKGROUND_INTENSITY 0x0080
*/

int main(int argc, char *argv[]){
    textcolor(1);
//  textcolor(FOREGROUND_BLUE);
    printf("FOREGROUND_BLUE \n");

    textcolor(4);
    printf("FOREGROUND_RED \n");

    textcolor(7);
    system("PAUSE");  
    return 0;
}

conio.h header file doesn't work with dev cpp because it is not part of c standard. http://www.bloodshed.net/dev/faq.html
