[Common-dev] RE: Resend new network API implementation for Symbian
Greg Wright gwright at real.com6K reduction in image size, nice. However, no attachments came through. Could you please resend with the attachments? Also, there is a size limit on attachments when sending to Helix mailing lists. You might have to send separate .txt files to each mailing list separately (or zip them). --greg.

It is defined by several new interfaces in common/include/hxnet.h. IHXSocket interface implementation provides the TCP/UDP socket functionality required by protocol and other modules. IHXSockAddrIN4 and IHXSockAddrIN6 implementation adds the support for ipv4 and ipv6 address classes. DNS resolution happens using IHXResolver interface. IHXNetServices is the glue that holds them together. >> >>Asynchronous events are sent using EventPending API. Client should always be prepared to handle the blocking errors in the read call. There is only one read operation could be outstanding any point of time. Multiple writes were required to be handled with the API. Therefore, a queue is used to handle such write calls. This implementation includes following: >> >>-AccessPointManager uses RConnection for connecting to access point. Asynchronous network connection is always completed before using Socket and other classes. At present, the client side Bind is not asynchronous but logic is in place to make Bind asynchronous in the socket implementation. Therefore, Bind assumes that network is connected which is true in almost all the cases. GetRConnection and GetRSocketServ are exposed from the AccessPointManager. >> >>-Multicast socket operations are implemented. >> >>-CHXSockAddrIN6 address class provides the IPV6 address functionality. >> >>-SHIM is disabled in build/umakepf/helix-client-s60-common.pfi. >> >>-KSockReadConitunation flag is used to reduce the excessive use of heap on high bit rate clips. This avoids the possible loss of datagram fragment due to truncation. Socket user will receive a datagram in multiple fragments if datagram size is larger than UDP_READ_SIZE_READCONTINUATION (4k). >> >> >>TODO: >> >>-asynchronous handling of Bind at the client side. >>-Testing is required for IPV6 based streaming. >> >> >>Testing was done with Helix Server, IMP server and QTSS.
