안녕하세요.. 갑자기 안되어서..질문을 올립니다...
if((s_fd = accept(server_fd,(struct sockaddr *)&s_addr, &s_len)) < 0) 여기에서 억셉트된 상대방 주소와 포트를 어떻게 뽑아내죠??
/******************************************************************************/ /* Wait Client Connection */ /* Prototype int WaitConnect(fd, buff) */ /* Arguments int fd; int socket discriptor */ /* char *buff; Client address buffer */ /* Return new socket fd */ /******************************************************************************/ int WaitConnect(fd, buff) int fd; char *buff; { int newfd, clilen; struct sockaddr_in cli_addr; unsigned char *p; clilen = sizeof(cli_addr); newfd=accept(fd, (struct sockaddr *)&cli_addr, &clilen); if(!buff) return newfd;
p = (unsigned char *)&cli_addr.sin_addr; sprintf(buff, "%3d.%3d.%3d.%3d", *p, *(p+1), *(p+2), *(p+3)); return newfd; }
