I would like to export some functions from my bettec dll for
dotnet core application in windows.
Right now I have compiled dll using dmd v2.091.0-dirty simply by
´dub build´
this is the function I have
extern(C) char* test_echo(const(char)* line, size_t len, ref
size_t resLen)
{
enum format = "{\"message\": \"%s\"}\n";
auto response = cast(char*)malloc(format.length + len);
resLen = sprintf(response, format, line);
return response;
}
and this is my dotnet core equivalent
[DllImport(DllName, CallingConvention =
CallingConvention.StdCall)]
static extern IntPtr
test_echo([MarshalAs(UnmanagedType.LPStr)]string line, ulong len,
out ulong resLen);
This works for me in linux but does not in windows, any idea what
I'm doing wrong?
This is the output from dotnet core
Unhandled exception. System.EntryPointNotFoundException: Unable
to find an entry point named 'test_echo' in DLL 'test.dll'
