| void display_show_force | ( | display_context_t | disp | ) |
Force-display a previously locked buffer.
Display a valid display context to the screen right away, without waiting for vblank interrupt. This function works also with interrupts disabled.
NOTE: this is currently not part of the public API as we use it only internally.
| [in] | disp | A display context retrieved using display_get |
