ldftn method |
Pushes a pointer to a method referenced by method on the stack. |
The stack transitional behavior, in sequential order, is:
-
The unmanaged pointer to a specific method is pushed onto the stack.
The specific method (method) can be called using the Calli instruction if it references a managed method (or a stub that transitions from managed to unmanaged code).
The value returned points to native code using the calling convention specified by the method metadata token. Thus, a method pointer can be easily passed to unmanaged native code (specifically, as a callback routine).
The following Emit method overload can use the ldftn opcode:
-
ILGenerator.Emit(OpCode, MethodInfo)
