Converts a delegate into a function pointer callable from unmanaged code.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

	Delegate d
)
public static IntPtr GetFunctionPointerForDelegate (
	Delegate d
)
public static function GetFunctionPointerForDelegate (
	d : Delegate
) : IntPtr

Parameters

d

The delegate to be passed to unmanaged code.

Return Value

An System.IntPtr value that can be passed to unmanaged code, which in turn can use it to call the underlying managed delegate.

Exception typeCondition

ArgumentNullException

The d parameter is a null reference (Nothing in Visual Basic).

The delegate d is converted to a function pointer that can be passed to unmanaged code.

Note that you must manually keep the delegate from being collected by the garbage collector (GC) from managed code. The GC does not track reference to unmanaged code.
