.SH DESCRIPTION
The body of \fBrtapi_app_exit\fR, which is provided by the component author,
generally consists of a call to rtapi_exit or hal_exit, preceded by other
component-specific shutdown code.
This code is called when unloading a component which successfully initialized
(i.e., returned zero from its \fBrtapi_app_main\fR). It is not called when
the component did not successfully initialize.
.SH RETURN CODE
None.
.SH REALTIME CONSIDERATIONS
Called automatically by the rtapi infrastructure in an initialization (not
realtime) context.
