/exports seçeneği
Açıklaması şöyle.

The MSVC linker can link together object files (.obj) and object libraries (.lib) to produce an .EXE or a .DLL.

To link with a DLL, the process in MSVC is to use a so-called import library (.LIB) that acts as a glue between the C function names and the DLL's export table (in a DLL a function can be exported by name or by ordinal - the latter was often used for undocumented APIs).

However, in most cases the DLL export table has all the function names and thus the import library (.LIB) contains largely redundant information ("import function ABC -> exported function ABC", etc).
It is even possible to generate a .LIB from an existing .DLL.

Örnek
Şöyle yaparız

dumpbin /EXPORTS yourfile.dll > yourfile.exports

Daha sonra şöyle yaparız. Çıktı olarak yourfile.lib ve yourfile.exp dosyalarını alırız.

vcvars32.bat

 lib /def:yourfile.def /out:yourfile.lib

64 bit için şöyle yaparız.

lib /def:yourfile.def /machine:x64 /out:yourfile64.lib

/section seçeneği
Şöyle yaparız

dumpbin /section:.debug$T /rawdata foo.obj > foo.txt

Dosyanın için şöyledir.
