I .inspected the parameters passed to the function that fails if that helps ;)
-----------
function => #<Library Symbol library=xml2 symbol=xmlSaveToIO
address=0x82b702da0>
args => [#<FFI::CallbackInfo [ pointer, string, int32 ], int32>,
#<FFI::CallbackInfo [ pointer ], int32>, #<FFI::Type::Builtin:POINTER size=8
alignment=8>, #<FFI::Type::Builtin:STRING size=8 alignment=8>,
#<FFI::Type::Builtin:INT32 size=4 alignment=4>]
ret => #<FFI::Type::Builtin:POINTER size=8 alignment=8>
options => {:convention=>:default, :type_map=>nil, :enums=>nil}
FFI::Invoker.new(function, args, find_type(ret), options)
