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 {ref}PRSockOption enumeration consists of all the socket options
supported by NSPR. The option field of {ref}PRSocketOptionData should
be set to an enumerator of type {ref}PRSockOption.
