C extension: How to create a Hash entry with Symbol key ?

[Iñaki Baz Castillo]

Hi, I do know how to create a hash from C in wich keys and values are strin=
gs:

VALUE hash =3D rb_hash_new();
rb_hash_aset(hash, rb_str_new("mykey",5), rb_str_new2(myvalue));

But now I want to create Hash entries with Symbol keys so the resulting Has=
h=20
would look like:
{ :mykey =3D> "lalala" }

By reading the C API documentation I don't find how to do it:

Any help please? Thanks a lot.

rb_hash_aset(hash, rb_str_new("mykey",5), rb_str_new2(myvalue));
=20
But now I want to create Hash entries with Symbol keys so the resulting
Hash would look like:
{ :mykey =3D> "lalala" }

ops, solved right now:

rb_hash_aset(hash, ID2SYM( rb_intern("mykey") ), rb_str_new2(myvalue));

This should do it.....

rb_hash_aset(hash, ID2SYM(rb_intern("mykey")), rb_str_new2(myvalue));
