I thought I understood this stuff cold... but now I wonder...
In this trivial program, the accept call fails with EINVAL. Go
figure. Any suggestions?
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
int
main(int ac, char **av) {
int server_port;
int server_fd;
int client_fd;
struct sockaddr_in sname;
int arg = sizeof(sname);
int one = 1;
server_port = 2001;
server_fd = socket(AF_INET, SOCK_STREAM, 0);
if (server_fd == -1)
perror("server socket failed");
setsockopt(server_fd, SOL_SOCKET, SO_REUSEADDR, (void *)&one, sizeof(one));
sname.sin_family = AF_INET;
sname.sin_port = htons((u_short)server_port);
sname.sin_addr.s_addr = INADDR_ANY;
if (bind(server_fd,(struct sockaddr *)&sname,sizeof(sname)))
perror("server bind failed");
client_fd = accept(server_fd,(struct sockaddr *)&sname,&arg);
if (client_fd == -1)
perror("client accept failed");
}
