Example #1

File: layer.c Project: xuzhenglun/Goo-OS

struct LAYER_CTL * layer_ctl_init(struct MEMMAN *man, unsigned char *vram, int xsize ,int ysize){
    struct LAYER_CTL *ctl;
    ctl = (struct LAYER_CTL *) mem_alloc_4k(man, sizeof(struct LAYER_CTL));
    if(ctl == 0){

    }
    ctl->map  = (unsigned char *)mem_alloc_4k(man,xsize*ysize);
    if(ctl->map == 0){
