NAME

       sdp_find_attribute - find the attribute from the attribute list

SYNOPSIS

       cc [ flag...] file... -lcommputil [ library...]
       #include <sdp.h>

       sdp_attr_t *sdp_find_attribute(sdp_attr_t *attr, const char *name);

DESCRIPTION

       The  sdp_find_attribute()  function searches the attribute list attr for the specified attribute name. If the attribute is found it returns
       the pointer to that attribute. Otherwise it returns NULL.

RETURN VALUES

       The sdp_find_attribute() function returns the attribute (sdp_attr_t *) on success and NULL when the search fails or  when  mandatory  input
       parameters are NULL.

EXAMPLES

       Example 1 An (incomplete) SDP description that contains one media section: audio.

	 m=audio 49170 RTP/AVP 0 8
	 a=rtpmap:0 PCMU/8000
	 a=rtpmap:8 PCMA/8000
	 a=sendonly
	 a=ptime:10000
	 a=maxptime:20000

	 /*
	  * Assuming that above description is parsed using sdp_parse and that
	  * the parsed structure is in "session" sdp_session_t structure.
	  */

	 sdp_attr_t *ptime;
	 sdp_attr_t *max_ptime;
	 sdp_media_t *media = session->s_media;

	 if ((ptime = sdp_find_attribute(media->m_attr, "ptime")) == NULL)
		 /* ptime attribute not present */
	 else if((max_ptime = sdp_find_attribute(media->m_attr,
		  "maxptime")) == NULL)
		 /* max_ptime attribute not present */
