Thanks.
I've implemented.
from fiddle.
Could you show a Ruby script that reproduces this case?
from fiddle.
Sure.
test.rb:
require 'fiddle'
require 'fiddle/import'
module MyModule
extend Fiddle::Importer
MyType = struct [
%q{void (*foo)(const char *value)}
]
end
closure = Class.new(Fiddle::Closure) {
def call(value)
puts "value! #{value}"
end
}.new(Fiddle::TYPE_VOID, [Fiddle::TYPE_CONST_STRING])
my_type = MyModule::MyType.malloc
my_type.foo = closure
# ...
fn = Fiddle::Function.new my_type.foo, [Fiddle::TYPE_CONST_STRING], Fiddle::TYPE_VOID
fn.call "bar"
Then:
% ruby test.rb
Traceback (most recent call last):
1: from test.rb:24:in `<main>'
test.rb:24:in `call': closure args: 10 (RuntimeError)
It seems like the behavior is specific to when closures are wrapped in a Function
.
