This mmtools itself is written in Delphi, from CallingConvention=CallingConvention. Cdecl this statement, mmtools. DLL should be done to Delphi version secondary packaging, and call in c #, true enough around, so you'd better look for Delphi version directly source code, there should be a demo can refer to,

In terms of the statement, so roughly:

Type
TagDeviceInfo=record
Ostype: string;
Devicebrand: string;
end;

Procedure WxSetDeviceInfo (pWorker: integer; PDeviceInfo: an array of tagDeviceInfo); Cdecl. External 'mmtools. DLL';

Procedure test.
Var
Worker: integer;
Dev: an array of tagDeviceInfo;
The begin
Worker:=0;//whether to initialise can try
SetLength (dev, 1);
WxSetDeviceInfo (worker, dev);
end;

Call the mmtools WxSetDeviceInfo of DLL,
