# FFI::NativeType

This module defines constants for native (C) types.

## 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 {FFI::Type::Builtin} class.
