How can I compare a nsAutoString to a c string?

Hi,

How can I compare a nsAutoString to a c string?

I have
nsAutoString mystring;

...

I try to compare it with 'test'. How can I do that?

I tried :
mystring.Equals("test")
and
strcmp(mystring.get(), "test") == 1

Both I can't get it to compile.

Thank you for any tip.
