Export function with variable number of args

[5k3l3t0r]

hi all,

i have a static lib that export some functions, the problem comes wen i try to export a function that uses C calling convenction and  VARARG:



myFunction proto C :DWORD,:VARARG

.code
myFunction proc C param:DWORD,args:VARARG

ret
myFunction endp



the .def

LIBRARY myLibrary.lib
EXPORTS func1 @1 --------------->this work ok
               func2 @2 --------------->this work ok
               myFunction @3  ------> can't call this function


i must export that function in some diferent way?

bye

C-style functions should have their exported names prefixed with underscore, try _myFunction ;)

hi Tedd

i have tried what you suggest and have build errors :

Code Select Expand


ReTool-2.0.def : error LNK2001: unresolved external symbol _RTCallModuleFunction
ReTool-2.0.def : error LNK2001: unresolved external symbol _RTLogMessageEx
ReTool-2.0.lib : fatal error LNK1120: 2 unresolved externals
LINK : fatal error LNK1141: failure during build of exports file


any other option?

you can see what the export names are by using something like dependency walker
or use one of Erol's tools - a number of ways to see what is exported by the lib

then - you will want a proper prototype
i suspect this is what may be missing

without the underscore the lib compile ok, but the i can't use the function in my exe that import that lib,
wen i try to compile the exe get
"error A2006: undefined symbol : RTLogMessageEx"
all other functions without the c style work ok

if i add the underscore to the def file, the lib wont compile...

this is the name in the export table:

maybe you could make an example library and post the source
it would be easier than each of us writing a lib   :P
