SILC_ASN1_OPTS(opts)

    The `opts' is SilcAsn1Options.  This macro can be used to set
    options for silc_asn1_encode and silc_asn1_decode functions.

    Only the SILC_ASN1_ALLOC and SILC_ASN1_ACCUMUL flags may be
    set with this macro.

    This macro must be the first macro in the variable argument list
    in the function.
