Hello,
Please send your answer to [EMAIL PROTECTED] because I do not read the
mailing list very often. Thanks.
I think I found a bug in cygwin. I open a socket connection and start a
child process after that. Then I cannot close the socket. The following is
a reduced source code with that problem. It works fine on Linux but not on
CygWin.
Compile and run it. The use "telnet localhost 80" to test it. You should
see the message "Hello" and then a disconnect message. But the disconnect
message is missed until you kill the child process.
#include <arpa/inet.h>
#include <netinet/in.h>
#include <stdio.h>
#include <string.h>
#include <sys/socket.h>
#include <unistd.h>
#include <signal.h>
#include <stdlib.h>
#include <errno.h>
#define PORT 80 // Port for TCP/IP Sockets
int main(int argc,char** argv)
{
struct sockaddr_in address;
int sock;
sock=socket(PF_INET,SOCK_STREAM,0);
setsockopt(sock,SOL_SOCKET,SO_REUSEADDR,0,0);
address.sin_family=AF_INET;
address.sin_port=htons(PORT);
memset(&address.sin_addr,0,sizeof(address.sin_addr));
bind(sock,(struct sockaddr *) &address,sizeof(address));
listen(sock,5);
{
size_t addrlength;
int verbindung;
addrlength=sizeof(address);
verbindung=accept(sock,(struct sockaddr *) &address,&addrlength);
if (verbindung>=0)
{
printf("Verbindung aufgebaut\n");
write(verbindung,"Hello\n",6);
if (fork()==0)
{
// Child
close(verbindung);
while (1)
{
printf("Child is running\n");
sleep(3);
}
exit(0);
}
else
{
// Mother
close(verbindung);
}
}
}
return 0;
}
