39 Internal worker function that reports a status code through the Status Code Protocol
41 This function checks to see if a Status Code Protocol is present in the handle
42 database. If a Status Code Protocol is not present, then EFI_UNSUPPORTED is
43 returned. If a Status Code Protocol is present, then it is cached in gStatusCode,
44 and the ReportStatusCode() service of the Status Code Protocol is called passing in
45 Type, Value, Instance, CallerId, and Data. The result of this call is returned.
47 @param Type Status code type.
48 @param Value Status code value.
49 @param Instance Status code instance number.
50 @param CallerId Pointer to a GUID that identifies the caller of this
51 function. This is an optional parameter that may be
53 @param Data Pointer to the extended data buffer. This is an
54 optional parameter that may be NULL.
56 @retval EFI_SUCCESS The status code was reported.
57 @retval EFI_OUT_OF_RESOURCES There were not enough resources to report the status code.
