#include <allegro5/allegro_native_dialog.h> ALLEGRO_TEXTLOG *al_open_native_text_log(char const *title, int flags)
Opens a window to which you can append log messages with al_append_native_text_log(3alleg5). This can be useful for debugging if you don\[aq]t want to depend on a console being available.
Use al_close_native_text_log(3alleg5) to close the window again.
The flags available are:
ALLEGRO_TEXTLOG_NO_CLOSE
Prevent the window from having a close button. Otherwise if the close button is pressed an event is generated; see al_get_native_text_log_event_source(3alleg5).
ALLEGRO_TEXTLOG_MONOSPACE
Use a monospace font to display the text.
Returns NULL if there was an error opening the window, or if text log windows are not implemented on the platform.
