If you are using the Allegro Game Library, you can do it like this

#include "allegro.h"
#include <stdio.h>
char SetVideoMode();

int main()
{
    allegro_init();
    install_keyboard();
    if(SetVideoMode())
    {
        line(screen, 0,0, 639, 479, 0xff0000);
        readkey();
    }
    else
    {
        printf("\nError setting video mode !\n");
        return 1;
    }
    return 0;
}

char SetVideoMode()
{    // return true if it worked
    set_color_depth(24);
    if ( ! (set_gfx_mode(640,480,0,0) ) )
        return 1;
    else
        return 0;
}
