Stream socket allows for reading arbitrary number of bytes, but still preserving byte sequence. In other words, a sender might write 4K of data to the socket, and the receiver can consume that data byte by byte. The other way around is true too - sender can write several small messages t...
int ret; sd = socket(PF_LOCAL, SOCK_DGRAM, 0); if (sd == -1) { perror("socket()"); goto socket_err; } hisend.sun_family = AF_UNIX; snprintf(hisend.sun_path, UNIX_PATH_MAX, "rcv_sock"); ret = connect(sd, (struct sockaddr *)&hisend, sizeof(hisend)); if (ret == -...
SOCK_DGRAM是基于UDP的,专门用于局域网,基于广播;SOCK_STREAM 是数据流,一般是tcp/ip协议的编程;SOCK_DGRAM是数据报,是udp协议网络编程 【AF_INET和AF_UNIX】 1、AF_INET不仅可以用作本机的跨进程通信,同样的可以用于不同机器之间的通信,其就是为了在不同机器之间进行网络互联传递数据而生。而AF_UNIX则只能用于...

libsocket supports the important socket types: INET/INET6 with TCP and UDP; and UNIX DGRAM/STREAM. Almost every function working with sockets is wrapped by libsocket, e.g.: - sendto - recvfrom - accept - socket/connect - one function - socket/bind - one function ...

unix domain socket示例一(SOCK_DGRAM) unix domain socket 是IPC通信的一种方式,可用于与管理进程间通信,同时由和网络socket统一,所以很好管理,使用还是比较多。现举个例子: server.c 1#include <stdio.h>2#include <string.h>3#include <unistd.h>4#include <stdlib.h>5#include <sys/types.h>6#include...
