Hello Javaranchers, I would like to know whether the java.net API supports all the socket options of the "socket.h" C library. Also, how should one make a choice of language while developing networking apps. Some criterion could be - Faster vs Platform-Independence Low level vs High level Thanks in advance Prasanna.

There are 4 socket options for java1.1, 6 options for java1.2 and 7 options for java1.3: TCP_NODELAY SO_BINDADDR SO_TIMEOUT SO_LINGER SO_SNDBUF //java1.2 and later SO_RCVBUF //java1.2 and later SO_KEEPALIVE //java1.3 and later Acccording to POSIX, there are 22 main socket options plus 26 additional ones. 22 main options here: //level: SOL_SOCKET //can be found in linux at sys/socket.h SO_BROADCAST SO_DEBUG SO_DONTROUTE SO_ERROR SO_KEEPALIVE SO_LINGER SO_OOBINLINE SO_RCVBUF SO_SNDBUF SO_RCVLOWAT SO_SNDLOWAT SO_RCVTIMEO SO_SNDTIMEO SO_REUSEADDR SO_REUSEPORT SO_TYPE SO_USELOOPBACK //level IPPROTO_TCP //under linux: linux/tcp.h TCP_KEEPALIVE TCP_MAXRT TCP_MAXSEG TCP_NODELAY TCP_STDURG so, choose according to your requirement.
