Public Enumeration CallingConvention

[ComVisibleAttribute(true)]
public enum CallingConvention

	Member name	Description
	Winapi	This member is not actually a calling convention, but instead uses the default platform calling convention. For example, on Windows the default is StdCall and on Windows CE.NET it is Cdecl.
	Cdecl	The caller cleans the stack. This enables calling functions with varargs, which makes it appropriate to use for methods that accept a variable number of parameters, such as Printf.
	StdCall	The callee cleans the stack. This is the default convention for calling unmanaged functions with platform invoke.
	ThisCall	The first parameter is the this pointer and is stored in register ECX. Other parameters are pushed on the stack. This calling convention is used to call methods on classes exported from an unmanaged DLL.
	FastCall	This calling convention is not supported.
