套接口地址结构(4)

学习笔记

Int fd;

Short events;

Short revents;

}

7.1 getsockopt 和setsockopt函数

1、

#include<sys/socket.h>

Int getsockopt(int sockfd,int level,int optname,void * optval,socklen_t * optlen);

Int setsockopt(int sockfd, int level, int optname, const void * optval, socklen_t optlen);

2、SO_LINGER套接口选项所需数据结构

Struct linger

{

Int l_onoff;

Int l_linger;

};

4、 SCTP_ASSOCINFO套接口选项气压数据结构

Struct sctp_assocparams

{

Sctp_assoc_t sasoc_assoc_id;

Uint16_t sasoc_asocmaxrxt;

Uint16_t sasoc_number_peer_destinations;

Uint32_t sasoc_peer_rwnd;

Uint32_t sasoc_local_rwnd;

Uint32_t sasoc_cookie_life;

};

5、 SCTP_DEFAULT_SEND_PARAM套接口选项所需数据结构

Struct sctp_sndrcvinfo

{

Uint16_t sinfo_stream;

Uint16_t sinfo_ssn;

Uint16_t sinfo_flags;

Uint32_t sinfo_ppid;

Uint32_t sinfo_context;

Uint32_t sinfo_timetolive;

Uint32_t sinfo_tsn;

Uint32_t sinfo_cumtsn;

Sctp_assoc_t sinfo_assoc_id;

};
