我不斷收到「警告:控制到達非void函數的終結」與此代碼:警告:控制到達非void函數結束(GTK)
static show_message(GtkMessageType type, const char* text, const char* details)
{
GtkWidget *dialog;
g_assert(text);
dialog = gtk_message_dialog_new(NULL, DIALOG_FLAGS, type, GTK_BUTTONS_CLOSE,
"%s", text);
if (details) {
gtk_message_dialog_format_secondary_text(GTK_MESSAGE_DIALOG(dialog), "%s", details);
}
gtk_dialog_run(GTK_DIALOG (dialog));
gtk_widget_destroy(dialog);
}
當我編譯上面的代碼中,我得到警告(即控制達到非無效功能結束):
gui.c: warning: return type defaults to 'int'
gui.c: In function 'show_message':
gui.c: warning: control reaches end of non-void function
如何擺脫此警告?
謝謝。
