+.Sh DESCRIPTION
+These functions manipulate
+.Vt ASN1_TYPE
+structures.
+An
+.Vt ASN1_TYPE
+structure can contain any ASN.1 type or constructed type such as a
+SEQUENCE: it is effectively equivalent to the ASN.1 ANY type.
+.Pp
+.Fn ASN1_TYPE_get
+returns the type of
+.Fa a .
+.Pp
+.Fn ASN1_TYPE_set
+sets the value of
+.Fa a
+to
+.Fa type
+and
+.Fa value .
+This function uses the pointer
+.Fa value
+internally so it must
+.Sy not
+be freed up after the call.
+.Pp
+.Fn ASN1_TYPE_set1
+sets the value of
+.Fa a
+to
+.Fa type
+and a copy of
+.Fa value .
+.Pp
+.Fn ASN1_TYPE_cmp
+compares ASN.1 types
+.Fa a
+and
+.Fa b .
+.Pp
+The type and meaning of the
+.Fa value
+parameter for
+.Fn ASN1_TYPE_set
+and
+.Fn ASN1_TYPE_set1
+is determined by the
+.Fa type
+parameter.
+If
+.Fa type
+is
+.Dv V_ASN1_NULL ,
+.Fa value
+is ignored.
+If
+.Fa type
+is
+.Dv V_ASN1_BOOLEAN ,
+then the boolean is set to TRUE if
+.Fa value
+is not
+.Dv NULL .
+If
+.Fa type
+is
+.Dv V_ASN1_OBJECT ,
+then
+.Fa value
+is an
+.Vt ASN1_OBJECT
+structure.
+Otherwise
+.Fa type
+is an
+.Vt ASN1_STRING
+structure.
+If
+.Fa type
+corresponds to a primitive type or a string type, then the contents
+of the
+.Vt ASN1_STRING
+contains the content octets of the type.
+If
+.Fa type
+corresponds to a constructed type or a tagged type
+.Pq Dv V_ASN1_SEQUENCE , V_ASN1_SET , No or Dv V_ASN1_OTHER ,
+then the
+.Vt ASN1_STRING
+contains the entire ASN.1 encoding verbatim, including tag and
+length octets.
+.Pp
+.Fn ASN1_TYPE_cmp
+may not return zero if two types are equivalent but have different
+encodings.
+For example the single content octet of the boolean TRUE value under BER
+can have any non-zero encoding but
+.Fn ASN1_TYPE_cmp
+will only return zero if the values are the same.
+.Pp
+If either or both of the parameters passed to
+.Fn ASN1_TYPE_cmp
+is
+.Dv NULL ,
+the return value is non-zero.
+Technically, if both parameters are
+.Dv NULL ,
+the two types could be absent OPTIONAL fields and so should match,
+however passing
+.Dv NULL
+Values could also indicate a programming error (for example an
+unparseable type which returns
+.Dv NULL )
+for types which do
+.Sy not
+match.
+So applications should handle the case of two absent values separately.
+.Sh RETURN VALUES
+.Fn ASN1_TYPE_get
+returns the type of the
+.Vt ASN1_TYPE
+argument.
+.Pp
+.Fn ASN1_TYPE_set1
+returns 1 for success or 0 for failure.
+.Pp
+.Fn ASN1_TYPE_cmp
+returns 0 if the types are identical or non-zero otherwise.
