Gintaras R. Gircys · Medical Entomology and Zoology · 1988
COFF, Common Object File Format, is the formal definition for the structure of machine code files in the UNIX System V.3 environment. All machine-code files--fully linked executables, compiled applications, or system libraries--are COFF files. There is hardly a system-related task that does not require some knowledge of COFF, from understanding assembly source to implementing a proprietary system enhancement. This handbook explains the COFF data structure and its manipulation.Contents include: Basics of COFF.Assembly code relocation process.COFF file headers.Relocation structures.Linking.The COFF system in UNIX.Magic numbers.The COFF symbolic debug system.
