Is shm_open supported in swift?
I can use shm_unlink but shm_open doesn't exist.
shm_open("/myregion", O_CREAT | O_RDWR)
If shm_open not supported in Swift is there an equivalent way to create a shared memory file descriptor for mapping?
I have managed to create shared memory in C but still not in Swift.
Turned out that shm_open works fine, it is just that swift can't use Variadic C functions.
I solved the problem by creating a new c file with the function:
int shmopen(const char *path) {
return shm_open(path, O_CREAT | O_RDWR, S_IRUSR | S_IWUSR);
}
Place the function in the "Project-Bridging-Header.h" file:
int shmopen(const char *path);
Call the function from swift:
var fd = shmopen("/myregion")
print(fd)
And now it works fine.
