The DUMPBIN Reference | Microsoft Docs[^] utility can do it for you.

what commands should i use? i tried several commands but couldn't get what i wanted; like /imports, it shows normal API names.

update: i was passing the .exe instead of the .lib file itself.

I would suggest probably /EXPORTS and /SYMBOLS would be a reasonable choice. See also Decorated names | Microsoft Docs[^].

+5; works with /EXPORTS

Thanks, it is a long time since I needed to use this.

The export with dumpbin works with User32.Lib as well as libuser32.a.

The function MessageBox is included in both, but in the VS version in the User32.Lib with underscore and with gcc in libuser32.a without underscore. In addition, the functions in the MS lib are also decorated.

"C:\...\VC\bin\dumpbin.exe"  /EXPORTS   "C:\...\x86\User32.Lib" >user32.lib.exports.txt
"C:\...\VC\bin\dumpbin.exe"  /EXPORTS   "C:\...\TDM-GCC-64\x86_64-w64-mingw32\lib\libuser32.a"
