Searched the internet and gone through the Help files, but I can't find a simple example on how to export a "stdcall" function from a C++ Builder DLL (I need to create an ISAPI with C++ Builder). Using the "exports" clause inside the unit doesn't do the export, so I guess it has to be declared in the main Project file or the DLL. But ... how do I do this? In Delphi, it's as simple as ... exports MyFunction; Does someone know how to do the same in C++ Builder? -- Danijel Tkalcec Back to top Michel Leunen Guest Posted: Sun Nov 27, 2005 10:25 am    Post subject: Re: Export a function from a C++Builder DLL "Danijel Tkalcec [RTC]" <dtkalcec (AT) hotmail (DOT) com> wrote in message Quote: Now I'm completely lost.

No, it is not a typedef. The use of WINAPI on that page is very deliberate. Microsoft documentation shows WINAPI in the help on the Windows API functions. Other companys' docs also use it. People will learn from that page. It seemed reasonable to present things on the page in a manner consistent with what they will see elsewhere. What the macro resolves to is also shown in that page, howto10.htm: -------------------------- WINAPI is a macro in the Windows header files. #define WINAPI __stdcall The keyword __stdcall specifies a type of calling convention (more about calling conventions below... -------------------------- ..
