从* .lib c ++调用

Question

Could someone please tell me how to call this type of function from a lib file (I got this from dumpbin /list ) here it is: 00A 00000000 SECT4 notype External | ?GetWindowPauseOnSizeMove_ext@@3P6G_NXZA (bool (__stdcall* GetWindowPauseOnSizeMove_ext)(void)) 00A 00000000 SECT4 notype External | ?GetWindowPauseOnSizeMove_ext@@3P6G_NXZA (bool (__stdcall* GetWindowPauseOnSizeMove_ext)(void))

I've tried

#pragma comment( lib, "MyLib" )
 extern "C" bool _stdcall GetWindowPauseOnSizeMove_ext(void)

But I Get this error

 Severity Code Description Project File Line Suppression State 

Error LNK2019 unresolved external symbol _GetWindowPauseOnSizeMove_ext@0 referenced in function _Test NF_dll D:\\Test\\Test\\main.obj 1

Any help will be great

According to the parameter mangling in the dumpbin list, it appears that the function has been actually compiled as C++.

Try to remove the extern "C" , and try to play with the calling convention ( __stdcall , _cdecl , __fastcall ).

If the http://demangler.com/ is correct, the function signature should be:

BOOL __stdcall GetWindowPauseOnSizeMove_ext(void)

Ie close to what you have, only with the C++ linkage instead of the C linkage.
