FunctionType

FunctionType represents C function.

Syntax

Returns a new CType object describing a C function.

CType FunctionType(
  abi,
  returnType[,
  argType1, ...]
);

abi: The ABI type for the function; this is one of the ABI constants.
returnType: A CType indicating the type of the value returned by the function.
argType1... argTypeN: Zero or more CType objects indicating the types of each of the parameters passed into the C function.

A CType describing the function type. The equivalent C function type declaration would be:

returnType (*) ([argType1, ..., argTypeN]);

TypeError: ABI is not a valid ABI constants, or returnType or any of the argument types are not valid CType objects.

Property	Type	Description
`abi`	One of the ABI constants	The ABI of the function. Read only.
`argTypes`	`CType[]`	A sealed array of the argument types. Read only.
`returnType`	`CType`	The return type of the function. Read only.

These properties are available on all CType objects.

Property	Type	Description
`name`	`String`	The type's name. Read only. For primitive types, this is just the name of the corresponding C type. For structure and opaque pointer types, this is simply the string that was passed to the constructor. For other function, pointer, and array types, this should be a valid C type expression.
`ptr`	CType	Returns a CType representing the data type "pointer to this type". This is the result of calling `ctypes.PointerType(the_type)`. Read only.
`size`	`Number`	The size of the type, in bytes. This is the same value as the C `sizeof`. Read only. Note: `ctypes.void_t.size` is undefined.

FunctionType CData cannot be constructed. Function pointer is created with FunctionType.ptr.

CData functiontype.ptr([func]);

functiontype is FunctionType CType.

A CData representing the newly allocated function pointer.
