static member GetFunctionPointerForDelegate : Delegate -> nativeintPublic Shared Function GetFunctionPointerForDelegate (d As Delegate) As IntPtrParameters
- d
- Delegate
The delegate to be passed to unmanaged code.
Returns
nativeint
A value that can be passed to unmanaged code, which, in turn, can use it to call the underlying managed delegate.
- Attributes
Exceptions
The d parameter is a generic type definition.
The d parameter is null.
Remarks
The delegate d is converted to a function pointer that can be passed to unmanaged code using the default platform calling convention. You can set the calling convention by applying the UnmanagedFunctionPointerAttribute to the delegate.
You must manually keep the delegate from being collected by the garbage collector from managed code. The garbage collector does not track references to unmanaged code.
