After some testing i found a solution, and it works. If anyone has any alternative and better method please let me know. Thank you :)

#include <gtk/gtk.h>

gboolean single = TRUE;

                  int n_press,

                  gdouble y,
                  gpointer user_data)

{
    if (n_press > 1) single = FALSE;
        longPress = FALSE;
}

void stopp_event (GtkGesture *gesture, gpointer user_data)
{
     if (single == FALSE){
         g_print("Double click\n");
     
     }else {
           if (longPress == FALSE)
               g_print("Single click\n");
     }
     single = TRUE;
     longPress = TRUE;
}
