@brief Creates a socket

@param[out] sockptr a pointer to the socket (file descriptor) created @param[in] domain the communication domain, selects the protocol family e.g. PF_INET, PF_PACKET @param[in] type specifies communication semantics e.g. SOCK_STREAM, SOCK_RAW @param[in] protocol specifies a particular protocol to be used with the socket e.g. IPPROTO_TCP, IPPROTO_UDP. Normally only a single protocol exists to support a particular socket type within a given protocol family, in which case protocol can be specified as 0. @return a DDS_RETCODE (OK, ERROR, NOT_ALLOWED, BAD_PARAMETER, OUT_OF_RESOURCES)
