linux shared memory 관련

shm으로 시작하는걸 찾으니 아래와 같이 나오는데

shm_open같은 shm_으로 시작하는 애들은 정체가...

POSIX 관련인가.. shm은 리눅스 쪽?

$ man -k shm shm_open (3)         - Create/open or unlink POSIX shared memory objects shm_overview (7)     - Overview of POSIX shared memory shm_unlink (3)       - Create/open or unlink POSIX shared memory objects shmat (2)            - shared memory operations shmctl (2)           - shared memory control shmdt (2)            - shared memory operations shmget (2)           - allocates a shared memory segment shmop (2)            - shared memory operations

#include <sys/ipc.h> #include <sys/shm.h> int shmget(key_t key, size_t size, int shmflg); shmflg = IPC_CREAT | IPC_EXCL; void *shmat(int shmid, const void *shmaddr, int shmflg); int shmdt(const void *shmaddr); int shmctl(int shmid, int cmd, struct shmid_ds *buf);

#include <sys/types.h> #include <sys/shm.h> void *shmat(int shmid, const void *shmaddr, int shmflg); int shmdt(const void *shmaddr);

다시 보니.. shm은 SystemV 계열

shm_ 은 POSIX 계열 인듯?
