Returns a pointer to the PDB file name for a PE/COFF image that has been
loaded into system memory with the PE/COFF Loader Library functions.
Returns the PDB file name for the PE/COFF image specified by Pe32Data. If
the PE/COFF image specified by Pe32Data is not a valid, then NULL is
returned. If the PE/COFF image specified by Pe32Data does not contain a
debug directory entry, then NULL is returned. If the debug directory entry
in the PE/COFF image specified by Pe32Data does not contain a PDB file name,
then NULL is returned.
