Detailed Description

Enumeration Type Documentation

   anonymous enum [protected]
       Enumerator

       defaultPathMTU

   enum SDESItemType
       SDES items that may be carried in a Source DEScription RTCP packet. CNAME is mandatory in
       each RTCP compound packet (except when split for partial encryption), the others are
       optional and have different sending frequencies, though with recommended default values.

       Enumerator

       SDESItemTypeEND
              END of SDES item list.

       SDESItemTypeCNAME
              Canonical end-point identifier.

       SDESItemTypeNAME
              Personal NAME of the user.

       SDESItemTypeEMAIL
              EMAIL address of the user.

       SDESItemTypePHONE
              Phone number of the user.

       SDESItemTypeLOC
              Location where the user is.

       SDESItemTypeTOOL
              Application or tool.

       SDESItemTypeNOTE
              Comment usually reporting state.

       SDESItemTypePRIV
              Private extension.

       SDESItemTypeH323CADDR
              H323 callable address.

       SDESItemTypeLast
              Last defined code.

   enum RTCPCompoundHandler::RTCPPacket::Type
       rtp.h cc++/rtp.h RTCP packet types. They are registered with IANA.

       Enumerator

       tSR    Sender Report.

       tRR    Receiver Report.

       tSDES  Source DEScription.

       tBYE   End of participation.

Function Documentation

   timeval NTP2Timeval (uint32 msw, uint32 lsw)
       Convert a NTP timestamp, expressed as two 32-bit long words, into a timeval value.

       Parameters:
           msw Integer part of NTP timestamp.
           lsw Fractional part of NTP timestamp.

       Returns:
           timeval value corresponding to the given NTP timestamp.

   uint32 timevalIntervalTo65536 (timeval & t)
       Convert a time interval, expressed as a timeval, into a 32-bit time interval expressed in
       units of 1/65536 seconds.

       Parameters:
           t Timeval interval.

       Returns:
           32-bit value corresponding to the given timeval interval.
