LoadInfo = object
  mVersion*: uint32          ## Contains the mIRC version number in the low and high words.
  mHwnd*: HWND               ## Contains the window handle to the main mIRC window.
  mKeep*: BOOL ## Is set to TRUE by default, indicating that mIRC will keep the
               ## dll loaded after the call. You can set mKeep to FALSE to make
               ## mIRC unload the dll after the call (which is how previous
               ## versions of mIRC worked).
  mUnicode*: BOOL ## Is set to FALSE by default, for backward compatibility. Can be
                  ## set to TRUE to indicate that strings are Unicode as opposed to
                  ## ANSI. Since mIRC v7.0.
  mBeta*: uint32 ## Contains the mIRC beta version number, for public betas. Since
                 ## mIRC v7.51.
  mBytes*: uint32 ## Specifies the maximum number of bytes (not characters) allowed in
                  ## the `data` and `parms` variables. Since mIRC v7.64.

Object received by the LoadDll() procedure when the dll is loaded in mIRC with $dll or /dll. Brings and takes information to mIRC. Since mIRC v5.8. Source   Edit  

ProcReturn {.importc: "int", nodecl, size: 4.} = enum
  RHalt = 0,                ## Means that mIRC should /halt processing.
  RContinue = 1,            ## Means that mIRC should continue processing.
  RCommand = 2, ## Means that the dll has filled the `data` or `result.outData`
                 ## variable with a command which it wants mIRC to perform, and has
                 ## filled `parms` or `result.outParms` with the parameters to use,
                 ## if any, when performing the command.
  RReturn = 3 ## Means that the dll has filled the `data` or `result.outData`
              ## variable with the result that $dll() identifier should return.

Values that can be returned by dll procedures. These values indicate what the mIRC should do. Since mIRC v5.6. Source   Edit  

UnloadMode {.importc: "int", nodecl, size: 4.} = enum
  MManual = 0, ## Unloaded with /dll -u. In versions older than mIRC v6.3 it may
                ## also be when mIRC exits.
  MUnused = 1, ## Dll not being used for ten minutes. The UnloadDll() procedure can
                ## return `RKeepLoaded` to keep the DLL loaded, or `RAllowUnload` to
                ## allow it to be unloaded.
  MOnExit = 2                ## Unloaded when mIRC exits. Since mIRC v6.3.

Values that indicate why the UnloadDll() procedure was called by mIRC. Since mIRC v5.8. Source   Edit  

UnloadReturn {.importc: "int", nodecl, size: 4.} = enum
  RKeepLoaded = 0,          ## Keep the dll loaded.
  RAllowUnload = 1           ## Allows the dll to be unloaded.

Return values for the UnloadDll() procedure. Since mIRC v5.8. Source   Edit
