Or was this it?
#ifdef __cplusplus
extern "C" {
#endif
extern void _RVExtensionVersion(char* p0, size_t p1);
extern void _RVExtensionArgs(char* p0, size_t p1, char* p2, char** p3, int p4);
extern void _RVExtension(char* p0, size_t p1, char* p2);
#ifdef __cplusplus
}
#endif
The 32-bit exports listed here,
https://community.bistudio.com/wiki/Extensions, are most likely what
is listed in the module-definition file ending in .def.
Can you please try using the following declaration:
//export RVExtension
func RVExtension(output *C.char, outputsize C.size_t, input *C.char) {...}
Compile your dll and post the output of dumpbin.exe /EXPORTS
/path/to/slib.dll showing the listing of your exported symbols?
