I have a question about "ruby/dl".

I define the function in "ruby/dl" like the belows


--------------------------------------
require 'dl'
LIB=DL.dlopen('libfunc.dll')
cfunc=LIB['cfunc','ISi'] # int cfunc(char *data,int *num)
---------------------------------------


After typing in irb, I typed them like this.


len=DL.malloc(DL.sizeof("I"))
err=cfunc.call("hello",len)


But, error message is displayed like the belows.


"TypeError: can't convert DL:trData into Integer"


I'm not sure how to solve the problem.

It makes me annoying


Please let me know the reason and solutions for novice like me.


Then, Thank you in advance.

Stop posting the same thing. If you don't get an answer, maybe you need to
restate your question.

Calm down. The same message, posted two minutes apart, probably means a
mail server hiccuped somewhere along the line, and probably doesn't mean
the poster had any intention to be rude or pushy.
