Using the sizeof(value) for deciding the buffer size is odd.
What if sizeof(int) is 4, but the value is 9999? The string will
need 5 bytes -- "9999" plus the zero termination. Instead try:
gchar buffer [16];
sprintf (buffer, "%d", value);
gtk_label_set_text (GTK_LABEL(label), buffer);
because 16 chars is a nice power of 2 that should be big enough to hold
value an int can throw at it with room to spare. if you're really
concerned about not using a fixed buffer:
gchar * buffer = g_strdup_printf ("%d", value);
gtk_label_set_text (GTK_LABEL(label), buffer);
g_free (buffer);
cheers,
Charles
