Expand description

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.
