Services API

Revision as of 10:29, 11 November 2016 by Mailwl (talk | contribs) (add boss:P to BOSS Services)

Nintendo provides application developers with an API, which communicate with certain services. Services, in this sense, are system processes running in the background which wait for incoming requests. When a process wants to communicate with a service, it first needs to get a handle to the named service, and then it can communicate with the service via interprocess communication. Each service has a name up to 8 characters, for example "nim:u".

Handles for services are retrieved from the service manager port, "srv:". Services are an abstraction of ports, they operate the same way except regular ports can have their handles retrieved directly from a SVC.

For a description of how commands and arguments are passed to services, see IPC Command Structure.

List of services (grouped by the process which provides them):
