/**
|
|
Register the callback function for ReportStatusCode() notification.
|
|
|
|
When this function is called the function pointer is added to an internal list and any future calls to
|
|
ReportStatusCode() will be forwarded to the Callback function. During the bootservices,
|
|
this is the callback for which this service can be invoked. The report status code router
|
|
will create an event such that the callback function is only invoked at the TPL for which it was
|
|
registered. The entity that registers for the callback should also register for an event upon
|
|
generation of exit boot services and invoke the unregister service.
|
|
If the handler does not have a TPL dependency, it should register for a callback at TPL high. The
|
|
router infrastructure will support making callbacks at runtime, but the caller for runtime invocation
|
|
must meet the following criteria:
|
|
1. must be a runtime driver type so that its memory is not reclaimed
|
|
2. not unregister at exit boot services so that the router will still have its callback address
|
|
3. the caller must be self-contained (eg. Not call out into any boot-service interfaces) and be
|
|
runtime safe, in general.
|
|
|
|
@param[in] Callback A pointer to a function of type EFI_RSC_HANDLER_CALLBACK that is called when
|
|
a call to ReportStatusCode() occurs.

|
@retval EFI_OUT_OF_RESOURCES The internal buffer ran out of space. No more functions can be
|
|
registered.
