Pushes an unmanaged pointer (type native int) to the native code implementing a particular virtual method associated with a specified object onto the evaluation stack.
Assembly: mscorlib (in mscorlib.dll)

Pushes the pointer to an object's virtual method method on the stack.
The stack transitional behavior, in sequential order, is:
An object reference is pushed onto the stack.
The object reference is popped from the stack and the address of the entry point to the method (as specified by the metadata token method) is looked up.
The pointer to method is pushed onto the stack.
The resulting unmanaged pointer pushed onto the stack by the ldvirtftn instruction can be called using the Calli instruction if it references a managed method (or a stub that transitions from managed to unmanaged code).
The unmanaged pointer points to native code using the calling convention specified by in the metadata token method. As a result, the method pointer can be passed to unmanaged native code (for example, as a callback routine) if that routine expects the corresponding calling convention.
The following Emit method overload can use the ldvirtftn opcode:
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
