[Dev-C++] Weird export table in dll

[Philip B. <phi...@pb...>]

Hi everone,

I'm in the process of building a voicechat dll for developers to allow =
them to add voicechat capabilities to their applications quickly and =
easily. I have just started so there is not much stuff implemented yet. =
I want it to work with the stdcall method and have a C interface. I =
think I've done everything right, but the export table looks really =
weird. It defines each function twice, first one without an @ # and then =
one with. Here is the export table:

PbTalker_Free
PbTalker_Free@0
PbTalker_GetInputDeviceCount
PbTalker_GetInputDeviceCount@0
PbTalker_GetInputDeviceName
PbTalker_GetInputDeviceName@4
PbTalker_GetLastError
PbTalker_GetLastError@0
PbTalker_GetLastErrorText
PbTalker_GetLastErrorText@0
PbTalker_GetOutputDeviceCount
PbTalker_GetOutputDeviceCount@0
PbTalker_GetOutputDeviceName
PbTalker_GetOutputDeviceName@4
PbTalker_Init
PbTalker_Init@0
PbTalker_SetHostAPI
PbTalker_SetHostAPI@4
PbTalker_StreamSound
PbTalker_StreamSound@4

Maybe I should metnion also that some of the functions return char *. =
The functions are declared like so:

#define exporting  __declspec( dllexport )
extern "C" exporting int __stdcall PbTalker_Init(void);
extern "C" exporting int __stdcall PbTalker_SetHostAPI(int);
extern "C" exporting int __stdcall PbTalker_GetInputDeviceCount(void);
extern "C" exporting const char* __stdcall =
PbTalker_GetInputDeviceName(int);
extern "C" exporting int __stdcall PbTalker_GetOutputDeviceCount(void);
extern "C" exporting const char* __stdcall =
PbTalker_GetOutputDeviceName(int);
extern "C" exporting int __stdcall PbTalker_GetLastError(void);
extern "C" exporting const char* __stdcall =
PbTalker_GetLastErrorText(void);
extern "C" exporting int __stdcall PbTalker_StreamSound(const char*);
extern "C" exporting int __stdcall PbTalker_Free(void);

In the project options, the compiler has the command line=20
parameter -mrtd set, and the linker has the following:
--no-export-all-symbols --add-stdcall-alias
Is it normal behavior, to export each function twice? If not, how can I =
fix it?
