The main top-level class that you instantiate once, or once per module.
Example usage:
ffi = FFI()
ffi.cdef("""
int printf(const char *, ...);
""")
C = ffi.dlopen(None) # standard library
-or-
C = ffi.verify() # use a C compiler: verify the decl above is right
C.printf("hello, %s!\n", ffi.new("char[]", "world"))

The types can be used in 'ffi.new()' and other functions.
If 'packed' is specified as True, all structs declared inside this
cdef are packed, i.e. laid out without any field alignment at all.
Alternatively, 'pack' can be a small integer, and requests for
alignment greater than that are ignored (pack=1 is equivalent to
packed=True).

z FFI.offsetofc C s" t |tr| |}| j||S )a Allocate an instance according to the specified C type and
return a pointer to it. The specified C type must be either a
pointer or an array: ``new('X *')`` allocates an X and returns
a pointer to it, whereas ``new('X[n]')`` allocates an array of
n X'es and returns an array referencing it (which works
mostly like a pointer, like in C). You can also use
``new('X[]', n)`` to allocate an array of a non-constant
length n.
The memory is initialized following the rules of declaring a
global variable in C: by default it is zero-initialized, but
an explicit initializer can be given which can be used to
fill all or part of the memory.
When the returned object goes out of scope, the memory
is freed. In other words the returned object has
ownership of the value of type 'cdecl' that it points to. This
means that the raw data can be used as long as this object is
kept alive, but must not be used for a longer time. Be careful
about that when copying the pointer to the memory somewhere
else, e.g. into another structure.

but uses the provided low-level 'alloc' and 'free' functions.
'alloc' is called with the size as argument. If it returns NULL, a
MemoryError is raised. 'free' is called with the result of 'alloc'
as argument. Both can be either Python function or directly C
functions. If 'free' is None, then no free function is called.
If both 'alloc' and 'free' are None, the default is used.
If 'should_clear_after_alloc' is set to False, then the memory
returned by 'alloc' is assumed to be already cleared (or you are
fine with garbage); otherwise CFFI will clear it.

zFFI.castc C s | j ||S )a Return a Python string (or unicode string) from the 'cdata'.
If 'cdata' is a pointer or array of characters or bytes, returns
the null-terminated string. The returned string extends until
the first null character, or at most 'maxlen' characters. If
'cdata' is an array then 'maxlen' defaults to its length.
If 'cdata' is a pointer or array of wchar_t, returns a unicode
string following the same rules.
If 'cdata' is a single character or byte or a wchar_t, returns
it as a string or unicode string.
If 'cdata' is an enum, returns the value of the enumerator as a
string, or 'NUMBER' if the value is out of range.

FFI.stringc C s | j ||S )aL Unpack an array of C data of the given length,
returning a Python string/unicode/list.
If 'cdata' is a pointer to 'char', returns a byte string.
It does not stop at the first null. This is equivalent to:
ffi.buffer(cdata, length)[:]
If 'cdata' is a pointer to 'wchar_t', returns a unicode string.
'length' is measured in wchar_t's; it is not the size in bytes.
If 'cdata' is a pointer to anything else, returns a list of
'length' items. This is a faster equivalent to:
[cdata[i] for i in range(length)]

Note that this is not meant to be used on the built-in types
str or unicode (you can build 'char[]' arrays explicitly)
but only on objects containing large quantities of raw data
in some other format, like 'array.array' or numpy arrays.
The first argument is optional and default to 'char[]'.

zFFI.from_bufferc C s | j |||S )a_ ffi.memmove(dest, src, n) copies n bytes of memory from src to dest.
Like the C function memmove(), the memory areas may overlap;
apart from that it behaves like the C function memcpy().
'src' can be any cdata ptr or array, or any Python buffer object.
'dest' can be any cdata ptr or array, or a writable Python buffer
object. The size to copy, 'n', is always measured in bytes.
Unlike other methods, this one supports all Python buffer including
byte strings and bytearrays---but it still does not support
non-contiguous buffers.

The callback invokes the specified 'python_callable' (which may
be provided either directly or via a decorator). Important: the
callback object must be manually kept alive for as long as the
callback may be invoked from the C level.

'destructor(old_cdata_object)' will be called.
The optional 'size' gives an estimate of the size, used to
trigger the garbage collection more eagerly. So far only used
on PyPy. It tells the GC that the returned object keeps alive
roughly 'size' bytes of external memory.

(including calling macros). This is unlike 'ffi.dlopen()',
