Expand description

sys_socket_send_handle - Send a kernel object handle through a socket

Transfers a kernel object (like SharedMemoryObject) to another task through a connected socket, similar to Unix SCM_RIGHTS functionality. Uses dup() semantics - the handle is duplicated, not moved, so both sender and receiver will have independent references to the same object.

Arguments:

  • socket_handle: Handle to the connected socket
  • object_handle: Handle to the kernel object to send (remains valid after send)

Returns:

  • 0 on success
  • usize::MAX on error
