[diso]

Sorry habe das bin Link geposted.. Sources: http://ngspice.sourceforge.net/ngspi..._src_delphi.7z

oder :

Code:

  ngspice_Init: function(ptrchar: Pointer; ptrstat: Pointer; ptrexit: Pointer;
                ptrdata: Pointer; ptrinitdata: Pointer; ptrnoruns: Pointer; userData: Pointer): integer; cdecl;
  ngspice_Com: function(ms: PChar): Integer; cdecl;
  ngspice_GetVec: function(ms: PChar): pVector_info; cdecl;
  ngspice_SendCirc: function(circarray: pcarray): Integer; cdecl;
  ngspice_GetCurPlot: function(): PChar; cdecl;
  ngspice_GetPlotNames: function(): ppansichararray; cdecl;
  ngspice_GetVecsFromPlot: function(plotname: PChar): ppansichararray; cdecl;
  ngspice_Running: function(): boolean; cdecl;
  ngspice_Init_Sync: function(ptrvsrcval: Pointer; ptrisrcval: Pointer; ptrsync: Pointer; ident: PInteger; userData: Pointer): integer; cdecl;
  ngspice_SetBkpt: function(simtime: double): boolean; cdecl;
