.SH "NAME"
ML_VRAM \- Video RAM and Display Driver management functions from libmonochrome
.SH "SYNOPSIS"
.sp
.nf
#include <monochrome\&.h>

char* ML_vram_address();
void ML_clear_vram();
void ML_clear_screen();
void ML_display_vram();
.fi
.SH "DESCRIPTION"
.sp
libmonochrome uses natively a double\-buffering technique : the user program draws on a working space, the VRAM, and when he finished drawing the frame, this frame is sent to the Display Driver so it can appear on the screen\&.
.sp
ML_vram_adress is a system call that returns the address of the VRAM allocated by the system\&. It is mainly meant for internal purposes, but if you want to use the VRAM directly, you can use it\&.
.sp
ML_clear_screen sends a bunch of zeros to the Display Driver so the screen content gets erased, but the VRAM stays as it is\&. ML_clear_vram does the opposite : it clears the VRAM content while leaving the screen\(cqs one\&.
.sp
ML_display_vram sends the VRAM content to the Display Driver, so it can appear on the screen\&.
