Parsing the SDP Session Structure

int sdp_parse(const char *sdp_info, int len, int flags,
              sdp_session_t **session, uint_t *p_error);

The sdp_parse() function parses the SDP description in the sdp_info parameter and populates the sdp_session_t structure. The len parameter specifies the length of the character buffer sdp_info. The function allocates the memory required for the sdp_session_t structure.

To free that memory, call the sdp_free_session() function. For more information, see Deleting an Attribute From the SDP Media Structure.

Example 2-5 Parsing an SDP Session Structure

In this example, the SDP session structure is as follows:

v=0\r\n
o=jdoe 23423423 234234234 IN IP4 192.168.1.1\r\n
s=SDP seminar\r\n
i=A seminar on the session description protocol\r\n
e=[e-mail]
c=IN IP4 192.168.90.1\r\n
t=2873397496 2873404696\r\n

After calling the sdp_parse_t() function, the resulting sdp_session_t structure is as follows:

session {
        sdp_session_version = 1
        s_version = 0
        s_origin {
                o_username = "jdoe"
                o_id = 23423423ULL
                o_version = 234234234ULL
                o_nettype = "IN"
                o_addrtype = "IP4"
                o_address = "192.168.1.1"
        }
        s_name = "SDP seminar"
        s_info = "A seminar on the session description protocol"
        s_uri =  (nil)
        s_email {
                value = "[e-mail]"
                next = (nil)
        }
        s_phone = (nil)
        s_conn {
                c_nettype = "IN"
                c_addrtype = "IP4"
                c_address = "192.168.90.1"
                c_addrcount = 0
                c_ttl = 0
                c_next = (nil)
        }
        s_bw = (nil)
        s_time {
                t_start = 2873397496ULL
                t_stop = 2873404696ULL
                t_repeat = (nil)
                t_next = (nil)
        }
        s_zone = (nil)
        s_key = (nil)
        s_attr = (nil)
        s_media = (nil)
