CommSession *	session	Session to send the response to.

MetaResponseInfo.payload

struct MetaResponseInfo.payload

Response payload.

Data Fields
uint16_t	endpoint_id	Endpoint ID the error refers to.
uint8_t	error_code	Error code, a MetaResponseCode.

Enumeration Type Documentation

MetaResponseCode

enum MetaResponseCode

Meta endpoint error code.

Enumerator
MetaResponseCodeNoError	No error.
MetaResponseCodeCorruptedMessage	Message could not be parsed; the response carries no endpoint ID.
MetaResponseCodeDisallowed	Sender is not allowed to use the endpoint.
MetaResponseCodeUnhandled	No handler for the endpoint.

Function Documentation

meta_endpoint_send_response_async()

void meta_endpoint_send_response_async

(

const MetaResponseInfo *

meta_response_info

)

Send a meta endpoint response asynchronously from KernelBG.

The response is copied, so meta_response_info need not outlive the call. Set payload.endpoint_id in CPU byte order; it is converted to big endian before sending.

Parameters

meta_response_info

Response to send.
