POINTER ( CodeContext context, IronPython.Runtime.Types.PythonType type ) : IronPython.Runtime.Types.PythonType	Returns a new type which represents a pointer given the existing type.
POINTER ( CodeContext context, [ name ) : IronPython.Runtime.Types.PythonType
PyObj_FromPtr ( IntPtr address ) : object	Converts an address acquired from PyObj_FromPtr or that has been marshaled as type 'O' back into an object.
PyObj_ToPtr ( object obj ) : IntPtr	Converts an object into an opaque address which can be handed out to managed code.
Py_DECREF ( object key ) : void	Decreases the ref count on an object which has been increased with Py_INCREF.
Py_INCREF ( object key ) : void	Increases the ref count on an object ensuring that it will not be collected.

Private Methods

Method	Description
Cast ( IntPtr data, IntPtr obj, IntPtr type ) : IntPtr	Implementation of our cast function. data is marshalled as a void* so it ends up as an address. obj and type are marshalled as an object so we need to unmarshal them.
CheckBits ( INativeType cdata, PythonTuple pt ) : int	Verifies that the provided bit field settings are valid for this type.
EmitCDataCreation ( INativeType type, ILGenerator method, List	Emits the marshalling code to create a CData object for reverse marshalling.
EnsureRefCountTable ( ) : void
GetFieldInfo ( INativeType type, object o, string &fieldName, INativeType &cdata, int &bitCount ) : void	Shared helper between struct and union for getting field info and validating it.
GetFieldsList ( object fields ) : IList	Shared helper to get the _fields_ list for struct/union and validate it.
GetFunctionType ( CodeContext context, int flags ) : CFuncPtrType
GetHandleFromObject ( object dll, string errorMsg ) : IntPtr
GetMarshalTypeFromSize ( int size ) : Type	Given a specific size returns a .NET type of the equivalent size that we can use when marshalling these values across calls.
IsPointer ( IronPython.Runtime.Types.PythonType pt ) : bool
MakeArrayType ( IronPython.Runtime.Types.PythonType type, int count ) : ArrayType
MakePointer ( CodeContext context, string name, PythonDictionary dict ) : PointerType
PerformModuleReload ( IronPython.Runtime.PythonContext context, PythonDictionary dict ) : void
StringAt ( IntPtr src, int len ) : IntPtr	Helper function for translating from memset to NT's FillMemory API.
StructureCannotContainSelf ( ) : Exception
ValidateArraySizes ( IronPython.Modules.ArrayModule array, int offset, int size ) : void
ValidateArraySizes ( System.Bytes bytes, int offset, int size ) : void
ValidateArraySizes ( int arraySize, int offset, int size ) : void
WStringAt ( IntPtr src, int len ) : IntPtr	Helper function for translating from memset to NT's FillMemory API.
