Function shm_open_anonymous::shm_open_anonymous

pub fn shm_open_anonymous() -> c_int

Creates an anonymous POSIX shared memory object.

On success, returns a new file descriptor as if by shm_open. The file descriptor is unnamed and cannot be unlinked.

On failure, returns -1 and sets errno.

Depending on operating system, this function may use an OS-specific system call for creating the memory object, or it may use a generic POSIX implementation.
