Problem with alleg42.dll / program crashes / Allegro & Codeblocks
- by user24152
I'm having a serious problem with allegro. The program should display random pixels on the screen and when I build and run it I get the following error message:
Below is the full code of my program:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include "allegro.h"
#define Text_Color_Red makecol(255,0,0)
int main()
{
    int ret;
    int color_depth = 32;
    int x;
    int y;
    int red;
    int green;
    int blue;
    int color;
    //init allegro
    allegro_init();
    //install keyboard
    install_keyboard();
    //set color depth to 32 bits
    set_color_depth(color_depth);
    //init random seed
    srand(time(NULL));
    //init video mode to 640 x 480
    ret = set_gfx_mode(GFX_AUTODETECT_WINDOWED,640,480,0,0);
    if(ret !=0)
    {
        allegro_message(allegro_error);
        return 1;
    }
    //Display string
    textprintf(screen,font,0,0,10,0,Text_Color_Red,"Screen Resolution is: %dx%d -- Press ESC to quit !",SCREEN_W,SCREEN_H);
    //display pixels until ESC key is pressed
   //wait for keypress
    while(!key[KEY_ESC])
    {
        //set a random location
        x = 10 + rand() % (SCREEN_W-20);
        y = 10 + rand() % (SCREEN_H-20);
        //set a random color
        red = rand() % 255;
        green = rand() % 255;
        blue = rand() % 255;
        color = makecol(red,green,blue);
        //draw the pixel
        putpixel(screen, x, y, color);
    }
    //quit allegro
    allegro_exit();
}
END_OF_MAIN()
