Extracts ASSERT() information from a status code structure. | |
Converts the status code specified by CodeType, Value, and Data to the ASSERT() | |
arguments specified by Filename, Description, and LineNumber. If CodeType is | |
an EFI_ERROR_CODE, and CodeType has a severity of EFI_ERROR_UNRECOVERED, and | |
Value has an operation mask of EFI_SW_EC_ILLEGAL_SOFTWARE_STATE, extract | |
Filename, Description, and LineNumber from the optional data area of the | |
status code buffer specified by Data. The optional data area of Data contains | |
a Null-terminated ASCII string for the FileName, followed by a Null-terminated | |
ASCII string for the Description, followed by a 32-bit LineNumber. If the | |
ASSERT() information could be extracted from Data, then return TRUE. | |
Otherwise, FALSE is returned. | |
