Struct x11rb::protocol::shm::AttachFdRequest

pub struct AttachFdRequest {
    pub shmseg: u32,
    pub shm_fd: OwnedFd,
    pub read_only: bool,
}

Create a shared memory segment.

Create a shared memory segment. The file descriptor will be mapped at offset zero, and the size will be obtained using fstat(). A zero size will result in a Value error.

Fields

• shmseg - A shared memory segment ID created with xcb_generate_id().
• shm_fd - The file descriptor the server should mmap().
• read_only - True if the segment shall be mapped read only by the X11 server, otherwise false.

Fields

shmseg: u32

shm_fd: OwnedFd

read_only: bool
