Subject: [B20.1 Win95] Problem with socket() function call.

Is there any reason that the socket() function call should return
EINPROGRESS?

I am seeing this happen with the following test program

-------------------- test.c --------------------
#include <stdio.h>

#include <errno.h>
#include <unistd.h>

#include <netdb.h>
#include <sys/socket.h>
#include <arpa/inet.h>

#define HOST "g1"
#define PORT 8080

int main()
{
 int serve,client,pid;
 int retval;
 struct sockaddr_in server;
 struct hostent* hp;
 int reuse_addr=1;
 int s;

 serve=socket(PF_INET,SOCK_STREAM,0);
 if(serve==-1)
   {fprintf(stderr,"Cannot create server socket [%d].\n",errno);return(1);}

 setsockopt(serve,SOL_SOCKET,SO_REUSEADDR,&reuse_addr,sizeof(reuse_addr));

 server.sin_family=AF_INET;
 server.sin_addr.s_addr=INADDR_ANY;
 server.sin_port=htons(PORT);

 retval=bind(serve,(struct sockaddr*)&server,sizeof(server));
 if(retval==-1)
   {fprintf(stderr,"Failed to bind server socket [%d].\n",errno);return(1);}

 listen(serve,4);

 client=accept(serve,(struct sockaddr*)0,(int*)0);

 if(client==-1)
   {fprintf(stderr,"Accept on server socket failed [%d].\n",errno);return(1);}

 pid=fork();

 if(pid==0)
   {
    close(serve);

    hp=gethostbyname(HOST);
    if(!hp)
      {fprintf(stderr,"Unknown host '%s' [%d].\n",HOST,h_errno);return(1);}

    memcpy((char*)&server.sin_addr,(char*)hp->h_addr,sizeof(server.sin_addr));

    server.sin_family=AF_INET;
    server.sin_port=htons((unsigned short)PORT);

    s=socket(PF_INET,SOCK_STREAM,0);
    if(s==-1)
      {fprintf(stderr,"Cannot create client socket [%d].\n",errno);return(1);}

    close(s);
    close(client);
   }
 else if(pid>0)
   {
    close(client);
    sleep(30);
    close(serve);
   }

 return(0);
}

Also is there likely to be a Beta 20.2 version of the DLL?
