[edk2-devel] [PATCH v5 30/38] MdePkg/IndustryStandard: PeImage.h: Import DLL characteristics
Posted by Ard Biesheuvel 1 year, 3 months ago
Add the various symbolic constants that the PE/COFF spec v8.3 defines
for the DllCharacteristics field of the PE optional header as
preprocessor macros so we can test for them in C code.
