The following is a wrapper function for the system call accept

The following is a wrapper function for the system call accept.  When a process is blocked in a slow system call such as accept,  and the process catches a signal, and the signal handler returns, the system call returns an error of  EINTR.  Since not all the interrupted system calls may automatically be started, modify the following code to restart the  accept when it is interrupted.

int Accept (int sockfd, SA* cliad dr, socklen_t* addrlen) 

{

  int n; 

 errno = 0; 

 if ((n = accept (sockfd, cliaddr, addrlen)) < 0)

 { 

 perror (“accept error”); Close (sockfd); 

 exit (1); 

  }

 return n;

}
