+ * asn1_get.c (asn1_get_tag): Deleted.
+ (asn1_get_tag_2): Renamed from asn1_get_tag_indef, now uses a
+ pointer to taginfo rather than a bunch of pointer args.
+ (asn1_get_id, asn1_get_length): Folded into asn1_get_tag_2.
+ (asn1_get_sequence): Call asn1_get_tag_2.
+ * asn1_get.h (taginfo): New structure.
+ (asn1_get_tag_indef, asn1_get_tag, asn1_get_id, asn1_get_length):
+ Declarations deleted.
+ (asn1_get_tag_2): Declare.
+ * asn1_decode.c (setup): Declare only a taginfo variable.
+ (asn1class, construction, tagnum, length): New macros.
+ (tag): Call asn1_get_tag_2.
+ * asn1_k_decode.c (next_tag, get_eoc, apptag, end_sequence_of,
+ end_sequence_of_no_tagvars, asn1_decode_krb5_flags): Call
+ asn1_get_tag_2; if no error, copy out values into scalar
+ variables.
+ (asn1_decode_ticket): Call asn1_get_tag_2.
+ * asn1buf.c (asn1buf_skiptail): Call asn1_get_tag_2.
+ * krb5_decode.c (check_apptag, next_tag, get_eoc): Call
+ asn1_get_tag_2; if no error, copy out values into scalar
+ variables.
+ (decode_krb5_enc_kdc_rep_part): Call asn1_get_tag_2.
+
2003-01-10 Ken Raeburn <raeburn@mit.edu>
* Makefile.in: Add AC_SUBST_FILE marker for libobj_frag.
