} 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.
