#define ksm_read 0X01#define ksm_rdwr 0x00struct ksm_info_t {    uint ksmsz; //size of shared mem    int cpid;   //pid of the creator    int mpid;   //pid of the last modifier    uint attached_nr; //number of attached processes    uint atime; //last attached time    uint dtime; //last deattach time    uint total_shrg_nr; //total number of existing shared regions    uint total_shpg_nr; //total number of existing shared pages};int ksmget(char* name, uint size);int ksmattach(int hd, int flag);int ksmdetach(int hd);int ksminfo(int hd, struct ksminfo_t* info);int ksmdelete(int hd);
