ErrorType A GUID that defines the format of the data returned in Buffer.
BufferSize The size, in bytes, of the data returned in Buffer.
Buffer A buffer that contains a Null-terminated Unicode string plus
some additional data whose format is defined by ErrorType.
Buffer is allocated by this function with AllocatePool()
,
and it is the caller’s responsibility to free it with a call to
FreePool()
.
Description
This function runs diagnostics on the controller specified by ControllerHandle and
ChildHandle. DiagnoticType specifies the type of diagnostics to perform on the controller
specified by ControllerHandle and ChildHandle. If the driver specified by This does
not support the language specified by Language, then EFI_UNSUPPORTED is returned. If the
controller specified by ControllerHandle and ChildHandle is not supported by the driver
specified by This, then EFI_UNSUPPORTED is returned. If the diagnostics type specified by
DiagnosticType is not supported by this driver, then EFI_UNSUPPORTED is returned. If
there are not enough resources available to complete the diagnostic, then
EFI_OUT_OF_RESOURCES is returned. If the controller specified by ControllerHandle
and ChildHandle passes the diagnostic, then EFI_SUCCESS is returned. Otherwise,
EFI_DEVICE_ERROR is returned.
If the language specified by Language is supported by this driver, then status information is
returned in ErrorType, BufferSize, and Buffer. Buffer contains a Null-terminated
Unicode string followed by additional data whose format is defined by ErrorType.
BufferSize is the size of Buffer is bytes, and it is the caller's responsibility to call
FreePool() on Buffer when the caller is done with the return data. If there are not enough
resources available to return the status information, then EFI_OUT_OF_RESOURCES is returned.
