Sure,
  "dll"  is the value returned by open_dll.
  "name" is the name of the library routine.
  "args" is a sequence that contains a list of the argument datatypes
expected by the library routine in question.

These values are defined in DLL.E

and I quote ...

-----------------------
global constant
  C_CHAR    = #01000001,
  C_UCHAR   = #02000001,
  C_SHORT   = #01000002,
  C_USHORT  = #02000002,
  C_INT     = #01000004,
  C_UINT    = #02000004,
  C_LONG    = C_INT,
  C_ULONG   = C_UINT,
  C_POINTER = C_ULONG,
  C_FLOAT   = #03000004,
  C_DOUBLE  = #03000008
