/**

Use the EFI Debug Image Table to lookup the FaultAddress and find which PE/COFF image
|
|
it came from. As long as the PE/COFF image contains a debug directory entry a
|
|
string can be returned. For ELF and Mach-O images the string points to the Mach-O or ELF
|
|
image. Microsoft tools contain a pointer to the PDB file that contains the debug information.
|
|
|
|
@param FaultAddress Address to find PE/COFF image for.
|
|
@param ImageBase Return load address of found image
|
|
@param PeCoffSizeOfHeaders Return the size of the PE/COFF header for the image that was found
|
|
|
|
@retval NULL FaultAddress not in a loaded PE/COFF image.
|
|
@retval Path and file name of PE/COFF image.
