==Native type constants Native types are defined by constants :

• INT8, SCHAR, CHAR
• UINT8, UCHAR
• INT16, SHORT, SSHORT
• UINT16, USHORT
• INT32,, INT, SINT
• UINT32, UINT
• INT64, LONG_LONG, SLONG_LONG
• UINT64, ULONG_LONG
• LONG, SLONG
• ULONG
• FLOAT32, FLOAT
• FLOAT64, DOUBLE
• POINTER
• CALLBACK
• FUNCTION
• CHAR_ARRAY
• BOOL
• STRING (immutable string, nul terminated)
• STRUCT (struct-b-value param or result)
• ARRAY (array type definition)
• MAPPED (custom native type) For function return type only :
• VOID For function argument type only :
• BUFFER_IN
• BUFFER_OUT
• VARARGS (function takes a variable number of arguments)

All these constants are exported to FFI module prefixed with "TYPE_". They are objets from Type::Builtin class.
