PRSockOption

Enumeration type used in the option field of PRSocketOptionData to form the name portion of a name-value pair.

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.
