Subject: rb_hash_aref and symbol keys

Hello

I'm just getting starting with ruby C extensions, and I'm having a
problem accessing hash values corresponding to keys which are symbols.
String keys work fine:

/* In ruby: myhash = { 'foo' => 'blah' } */
foo = rb_hash_aref(myhash, rb_str_new2("foo")); /* works */

/* In ruby: myhash = { :foo => 'blah' } */
foo = rb_hash_aref(myhash, rb_intern("foo")); /* returns Qnil :( */

What is the proper way to do that? I found someone with the same problem
in the archives, but I'm afraid I didn't understand Nobu's answer in
ruby-talk:86571 :\

Thanks in advance,
Andre
