PROBLEM: Passing optional args to a function !!!

hello friends,

Look at the snap of code below:

Code:

---

void
set_color(GtkWidget *widget, int state, char* fg_color, char* bg_color = "")
{
    GdkColor color_fg, color_bg;
   
    if(bg_color == "")
    {
        gdk_color_parse(fg_color, &color_fg);
        gtk_widget_modify_fg(widget, state, &color_fg);
    }
    else
    {
        gdk_color_parse(fg_color, &color_fg);
        gdk_color_parse(bg_color, &color_bg);
   
        gtk_widget_modify_fg(widget, state, &color_fg);
        gtk_widget_modify_bg(widget, state, &color_bg);   
    }
}

---

This code is giving me the error:

Code:

---

error: expected ‘;’, ‘,’ or ‘)’ before ‘=’ token.

---

in the line:

Code:

---

set_color(GtkWidget *widget, int state, char* fg_color, char* bg_color = "")

---

Can anyone help me please.

C doesn't support optional ( better default ) parameters.

Thanks a lot Zuk. I will modify my code accordingly.

Guess you were lucky. Kurt

Code:

---

    if(bg_color == "")

This wouldn't work anyway. It is comparing pointers.
Use strcmp() instead.
