Typedef Name

Description

Handler) (const Request request, const Response response)

typedef void(*

Handles asynchronous responses.

Function Name	Description
SAMGR_SendRequest (const Identity identity, const Request request, Handler handler)	int32 Sends a request to a service or feature of a specified identity.
SAMGR_SendSharedRequest (const Identity identity, const Request request, uint32 token, Handler handler)	uint32 Sends a request to multiple services or features to save memory.
SAMGR_SendSharedDirectRequest (const Identity id, const Request req, const Response resp, uint32 ref, Handler handler)	int32 Sends a request and response of a caller to the feature thread. The handler is directly called to process the request and response without using the message processing functions. (Customized function for the broadcast service)
SAMGR_SendResponse (const Request request, const Response response)	int32 Sends a response after processing a request.
SAMGR_SendResponseByIdentity (const Identity id, const Request request, const Response response)	int32 Sends a response to a specified service or feature after processing the original request. (Customized function for bootstrap)
