Struct wayland_client::protocol::wl_shm::WlShm
source · pub struct WlShm { /* private fields */ }
Expand description
shared memory support
A singleton global object that provides support for shared memory.
Clients can create wl_shm_pool objects using the create_pool request.
On binding the wl_shm object one or more format events are emitted to inform clients about the valid pixel formats that can be used for buffers.
See also the Event enum for this interface.

create a shm pool
Create a new wl_shm_pool object.
The pool can be used to create shared memory based buffer objects. The server will mmap size bytes of the passed file descriptor, to use as backing memory for the pool.
