Function Documentation

errval_t ump_endpoint_deregister

(

struct ump_endpoint *

ep

)

Cancel an event registration made with ump_endpoint_register()

Parameters

ep	UMP Endpoint

errval_t ump_endpoint_init	(	struct ump_endpoint *	ep,
		volatile void *	buf,
		size_t	bufsize
	)

Initialise a new UMP endpoint.

Parameters

ep	Storage for endpoint state
buf	Pointer to incoming message buffer
bufsize	Size of buf in bytes (must be multiple of UMP message size)

void ump_endpoint_migrate	(	struct ump_endpoint *	ep,
		struct waitset *	ws
	)

Migrate an event registration made with ump_endpoint_register() to a new waitset.

Parameters

ep	LMP Endpoint
ws	New waitset

errval_t ump_endpoint_register	(	struct ump_endpoint *	ep,
		struct waitset *	ws,
		struct event_closure	closure
	)

Register an event handler to be notified when messages can be received.

In the future, call the closure on the given waitset when it is likely that a message can be received on the endpoint. An endpoint may only be registered with a single event handler on a single waitset at any one time.

Parameters

ep	UMP endpoint
ws	Waitset
closure	Event handler
