} PRSockOption;
Enumerators
The enumeration has the following enumerators:
PR_SockOpt_Nonblocking- Nonblocking I/O.
PR_SockOpt_Linger- Time to linger on close if data is present in the socket send buffer.
PR_SockOpt_Reuseaddr- Allow local address reuse.
PR_SockOpt_Keepalive- Periodically test whether connection is still alive.
PR_SockOpt_RecvBufferSize- Receive buffer size.
PR_SockOpt_SendBufferSize- Send buffer size.
PR_SockOpt_IpTimeToLive- IP time-to-live.
PR_SockOpt_IpTypeOfService- IP type-of-service and precedence.
PR_SockOpt_AddMember- Join an IP multicast group.
PR_SockOpt_DropMember- Leave an IP multicast group.
PR_SockOpt_McastInterface- IP multicast interface address.
PR_SockOpt_McastTimeToLive- IP multicast time-to-live.
PR_SockOpt_McastLoopback- IP multicast loopback.
PR_SockOpt_NoDelay- Disable Nagle algorithm. Don't delay send to coalesce packets.
PR_SockOpt_MaxSegment- Maximum segment size.
PR_SockOpt_Last- Always one greater than the maximum valid socket option numerator.
Description
The PRSockOption enumeration consists of all the socket options supported by NSPR. The option field of PRSocketOptionData should be set to an enumerator of type PRSockOption.
