Subject: Make krb5_preauth_context a pointer type
X-Git-Tag: krb5-1.16-beta1~159
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=459a081dec6e91ae480a37acb805631742afe1e2;p=thirdparty%2Fkrb5.git

Make krb5_preauth_context a pointer type

For consistency with krb5_context and krb5_init_creds_context, make
krb5_preauth_context a pointer type.  In preauth2.c, use the typedef
name rather than the structure tag except when defining the structure.
