Function krb5_rc_close not declared

[Milan Ševčík]

During maintenance update of our very old tool I found out, that the 
function krb5_rc_close is not declared in any public header. Using macro 
krb5_x in the same way as it is used by that function is also 
impossible, since the structure krb5_rcache is not defined.

I would just like to know, if any rcache handling is being considered 
deprecated, or if it was just omitted by mistake in the time the headers 
were refactored.

Thank you for your answer,
