ffi_type_void
-
The type void. This cannot be used for argument types, only
for return values.
ffi_type_uint8
-
An unsigned, 8-bit integer type.
ffi_type_sint8
-
A signed, 8-bit integer type.
ffi_type_uint16
-
An unsigned, 16-bit integer type.
ffi_type_sint16
-
A signed, 16-bit integer type.
ffi_type_uint32
-
An unsigned, 32-bit integer type.
ffi_type_sint32
-
A signed, 32-bit integer type.
ffi_type_uint64
-
An unsigned, 64-bit integer type.
ffi_type_sint64
-
A signed, 64-bit integer type.
ffi_type_float
-
The C float type.
ffi_type_double
-
The C double type.
ffi_type_uchar
-
The C unsigned char type.
ffi_type_schar
-
The C signed char type. (Note that there is not an exact
equivalent to the C char type in libffi; ordinarily you
should either use ffi_type_schar or ffi_type_uchar
depending on whether char is signed.)
ffi_type_ushort
-
The C unsigned short type.
ffi_type_sshort
-
The C short type.
ffi_type_uint
-
The C unsigned int type.
ffi_type_sint
-
The C int type.
ffi_type_ulong
-
The C unsigned long type.
ffi_type_slong
-
The C long type.
ffi_type_longdouble
-
On platforms that have a C long double type, this is defined.
On other platforms, it is not.
ffi_type_pointer
-
A generic void * pointer. You should use this for all
pointers, regardless of their real type.
ffi_type_complex_float
-
The C _Complex float type.
ffi_type_complex_double
-
The C _Complex double type.
ffi_type_complex_longdouble
-
The C _Complex long double type.
On platforms that have a C long double type, this is defined.
On other platforms, it is not.
