/* Attribute access routines are all defined by the following parameters.
 *
 * sdp_ptr     The SDP handle returned by sdp_init_description.
 * level       The level the attribute is defined.  Can be either
 *             SDP_SESSION_LEVEL or 0-n specifying a media line level.
 * inst_num    The instance number of the attribute.  Multiple instances
 *             of a particular attribute may exist at each level and so
 *             the inst_num determines the particular attribute at that
 *             level that should be accessed.  Note that this is the
 *             instance number of the specified type of attribute, not the
 *             overall attribute number at the level.  Also note that the
 *             instance number is 1-based.  For example:
 *             v=0
 *             o=mhandley 2890844526 2890842807 IN IP4 126.16.64.4
 *             s=SDP Seminar
 *             c=IN IP4 10.1.0.2
 *             t=0 0
 *             m=audio 1234 RTP/AVP 0 101 102
 *             a=foo 1
 *             a=foo 2
 *             a=bar 1   # This is instance 1 of attribute bar.
 *             a=foo 3   # This is instance 3 of attribute foo.
 * cap_num     Almost all of the attributes may be defined as X-cpar
 *             parameters (with the exception of X-sqn, X-cap, and X-cpar).
 *             If the cap_num is set to zero, then the attribute is not
 *             an X-cpar parameter attribute.  If the cap_num is any other
 *             value, it specifies the capability number that the X-cpar
 *             attribute is specified for.
 */

/* Attribute handling:
 *
 * There are two basic types of attributes handled by the SDP library,
 * those defined by a= token lines, and those embedded with a=X-cpar lines.
 * The handling for each of these is described here.
 *
 * Simple (non X-cpar attributes):
 *
 * Attributes not embedded in a=X-cpar lines are referenced by level and
 * instance number.  For these attributes the capability number is always
 * set to zero.
 *
 * An application will typically process these attributes in one of two ways.
 * With the first method, the application can determine the total number
 * of attributes defined at a given level and process them one at a time.
 * For each attribute, the application will query the library to find out
 * what type of attribute it is and which instance within that type. The
 * application can then process this particular attribute referencing it
 * by level and instance number.
 *
 * A second method of processing attributes is for applications to determine
 * each type of attribute they are interested in, query the SDP library to
 * find out how many of that type of attribute exist at a given level, and
 * process each one at a time.
 *
 * X-cpar attribute processing:
 *
 * X-cpar attributes can contain embedded attributes.  They are associated
 * with X-cap attribute lines.  An example of X-cap and X-cpar attributes
 * found in an SDP is as follows:
 *
 * v=0
 * o=- 25678 753849 IN IP4 128.96.41.1
 * s=-
 * t=0 0
 * c=IN IP4 10.1.0.2
 * m=audio 3456 RTP/AVP 18 96
 * a=rtpmap:96 telephone-event/8000
 * a=fmtp:96 0-15,32-35
 * a=X-sqn: 0
 * a=X-cap: 1 audio RTP/AVP 0 18 96 97
 * a=X-cpar: a=fmtp:96 0-16,32-35
 * a=X-cpar: a=rtpmap:97 X-NSE/8000
 * a=X-cpar: a=fmtp:97 195-197
 * a=X-cap: 5 image udptl t38
 * a=X-cap: 6 application udp X-tmr
 * a=X-cap: 7 audio RTP/AVP 100 101
 * a=X-cpar: a=rtpmap:100 g.711/8000
 * a=X-cpar: a=rtpmap:101 g.729/8000
 *
 * X-cap attributes can be defined at the SESSION_LEVEL or any media level.
 * An X-cap attr is defined by the level and instance number just like
 * other attributes.  In the example above, X-cap attrs are defined at
 * media level 1 and there are four instances at that level.
 *
 * The X-cpar attributes can also be referenced by level and instance number.
 * However, the embedded attribute within an X-cpar attribute must be
 * referenced by level, instance number, and capability number.  This is
 * because the X-cpar attribute is associated with a particular X-cap/
 * capability.
 * For all attributes that are not embedded within an X-cpar attribute, the
 * cap_num should be referenced as zero.  But for X-cpar attributes, the
 * cap_num is specified to be one of the capability numbers of the previous
 * X-cap line.  The number of capabilities specified in an X-cap line is
 * equal to the number of payloads.  Thus, in this example, the first X-cap
 * attr instance specifies capabilities 1-4, the second specifies capability
 * 5, the third capability 6, and the fourth capabilities 7-8.
 *
 * X-cpar attributes can be processed with methods similar to the two
 * previously mentioned.  For each X-cap attribute, the application can
 * use one of two methods to process the X-cpar attributes.  First, it
 * can query the total number of X-cpar attributes associated with a
 * given X-cap attribute.  The X-cap attribute is here defined by a level
 * and a capability number.  In the example above, the total number of
 * attributes defined is as follows:
 *  level 1, cap_num 1 - total attrs: 3
 *  level 1, cap_num 5 - total attrs: 0
 *  level 1, cap_num 6 - total attrs: 0
 *  level 1, cap_num 7 - total attrs: 2
 *
 * Note that if the application queried the number of attributes for
 * cap_num 2, 3, or 4, it would also return 3 attrs, and for cap_num
 * 8 the library would return 2.
 *
 * Once the application determines the total number of attributes for
 * that capability, it can again query the embedded attribute type and
 * instance.  For example, sdp_get_attr_type would return the following:
 *  level 1, cap_num 1, attr 1 -> attr type fmtp, instance 1
 *  level 1, cap_num 1, attr 2 -> attr type rtpmap, instance 1
 *  level 1, cap_num 1, attr 3 -> attr type fmtp, instance 2
 *  level 1, cap_num 7, attr 1 -> attr type rtpmap, instance 1
 *  level 1, cap_num 7, attr 2 -> attr type rtpmap, instance 2
 *
 * The individual embedded attributes can then be accessed by level,
 * cap_num, and instance number.
 *
 * With the second method for handling X-cpar attributes, the application
 * determines the types of attributes it is interested in.  It can then
 * query the SDP library to determine the number of attributes of that
 * type found for that level and cap_num, and then process each one at
 * a time.  e.g., calling sdp_attr_num_instances would give:
 *  level 1, cap_num 1, attr_type fmtp -> two instances
 *  level 1, cap_num 1, attr_type rtpmap -> one instance
 *  level 1, cap_num 7, attr_type fmtp -> zero instances
 *  level 1, cap_num 7, attr_type rtpmap -> two instances

/* Function:    sdp_copy_attr
 * Description: Copy an attribute from one SDP/level to another. A new

 *              list at the dst SDP/level and all parameter values are
 *              copied.
 * Description: Add a new attribute of the specified type at the given
 *              level and capability level or base attribute if cap_num
 *              is zero.
 * Parameters:  src_sdp_ptr The source SDP handle.
 *              dst_sdp_ptr The dest SDP handle.
 *              src_level   The level of the source attribute.
 *              dst_level   The level of the source attribute.
 *              src_cap_num The src capability number associated with the
 *                          attribute if any.
 *              dst_cap_num The dst capability number associated with the
 *                          attribute if any. Note that src and dst
 *                          cap_num must both be zero or both be non-zero.
 *              src_attr_type  The type of source attribute. This cannot
 *                             be SDP_ATTR_X_CAP or SDP_ATTR_X_CPAR.
 *              src_inst_num   The instance number of the source attr.
 * Returns:     SDP_SUCCESS    Attribute was successfully copied.

 *              This assumes you cannot have both versions in the same SDP.
 *
 * Parameters:  sdp_ptr     The SDP handle returned by sdp_init_description.
 *              level       The level to check for the attribute.
 *              cap_num     The capability number associated with the

 *              inst_num    The attribute instance number to check.
 *              mki_value   buffer containing the mki value. Assumes null
 *                          terminated buffer.
 *              mki_length  length of the MKI
 * Returns:     SDP_SUCCESS            Attribute param was set successfully.
