Linux学习笔记 socket accept错误14 Bad address

Linux学习笔记 socket accept错误14 Bad address

socket
bind
listen
都正常，在accept时报错accept error:14,Bad address，
代码如下：

	/* Now we can accept incoming connections oneat a time using accept. */struct sockaddr_in client_sockaddr;bzero(&client_sockaddr, sizeof(client_sockaddr));int cfd = accept(g_tcpserver_sfd, (struct sockaddr*)&client_sockaddr,sizeof(client_sockaddr));if (cfd == -1){sprintf(err, "accept error:%d,%s", errno, strerror(errno));return FALSE;}

报错：accept error:14,Bad address，

accept 原型参考1
accept 原型参考2

 #include <sys/socket.h>int accept(int sockfd, struct sockaddr *restrict addr,socklen_t *restrict addrlen);

注意最后一个参数是 socklen_t *restrict addrlen
代码修改为

	/* Now we can accept incoming connections oneat a time using accept. */struct sockaddr_in client_sockaddr;bzero(&client_sockaddr, sizeof(client_sockaddr));socklen_t acceptsize = sizeof(struct sockaddr);int cfd = accept(g_tcpserver_sfd, (struct sockaddr*)&client_sockaddr,&acceptsize);if (cfd == -1){sprintf(err, "accept error:%d,%s", errno, strerror(errno));return FALSE;}

运行正常
