Is it possible to export an EXE function like we do with DLLs? My EXE loads a DLL. I would like that my DLL could use a function in my EXE.
Is this possible?
Thanks in advance.
when you link your exe,
us link /SUBSYTEM:WINDOWS /EXPORT:nameoffunctiontoexport yourexe.obj
Below sample code would export one function. and call it from itself.
to compile and test
;ml /c /coff /Cp exportexe.asm
;link /SUBSYSTEM:WINDOWS /EXPORT:MyExeExPort exportexe.obj
;
.586
.model flat, stdcall
MyExeExport proto :DWORD, :DWORD
include d:\masm32\include\windows.inc
include d:\masm32\include\kernel32.inc
include d:\masm32\include\user32.inc
includelib d:\masm32\lib\user32.lib
includelib d:\masm32\lib\kernel32.lib
.data
szExe db "exportexe.exe",0
exExport db "MyExport",0
.code
start:
invoke LoadLibrary, addr szExe
.if eax
push eax
invoke GetProcAddress, eax, addr exExport
.if eax
push offset szExe
push offset exExport
call eax
.endif
pop eax
invoke FreeLibrary, eax
.endif
invoke ExitProcess, eax
MyExport proc public pq, pd
invoke MessageBox, NULL, pq, pd, NULL
ret
MyExport endp
end start
ps.
If you want to test this just compile and link it. Then Rename
it to something else, then compile and link again.
or just run it by itself.
take care

You could always just create a DEF file, in exactly the same way as for a DLL, but make sure you include it when you build the executable.
Once you've exported the functions you can generate a LIB file and use it during linking in the normal way, rather than calling the GetProcAddress function.
