Returns data for each server connection.

      void  svc_getreqset(fd_set *rdfds);

1  –  Arguments

 rdfds
    A pointer to the read file descriptor bit mask modified by the
    select routine.

2  –  Description

    The svc_getreqset routine is for servers that implement custom
    asynchronous event processing or that do not use the svc_run
    routine. You can only use svc_fdset when the server does not use
    svc_run.

    You are unlikely to call this routine directly, because the
    svc_run routine calls it. However, there are times when you
    cannot call svc_run. For example, suppose a program services
    RPC requests and reads or writes to another socket at the same
    time. The program cannot call svc_run. It must call select and
    svc_getreqset.

    The server calls svc_getreqset when a call to the select system
    call determines that the server has received one or more RPC
    requests. The svc_getreqset routine reads in data for each server
    connection, then calls the server program to handle the data.

    The svc_getreqset routine does not return a value. It finishes
    executing after all sockets associated with the variable rdfds
    have been serviced.

    You can use the global variable svc_fdset with svc_getreqset. The
    svc_fdset variable is the RPC server's read file descriptor bit
    mask.

    To use svc_fdset:
    1. Copy the global variable svc_fdset into a temporary variable.
    2. Pass the temporary variable to the select routine. The select
       routine overwrites the variable and returns it.
    3. Pass the temporary variable to the svc_getreqset routine.

3  –  Example

  #define MAXSOCK 10
       int readfds[ MAXSOCK+1],    /* sockets to select from*/
           i, j;
       for(i = 0, j = 0; i << MAXSOCK; i++)
            if((svc_fdset[i].sockname != 0) && (svc_
 fdset[i].sockname != -1))
                 readfds[j++] = svc_fdset[i].sockname;
       readfds[j] = 0;                 /* list of sockets ends with a zero */
       switch(select(0, readfds, 0, 0, 0))
       {
         case -1:      /* an error happened */
         case 0:       /* time out */
              break;
         default:      /* 1 or more sockets ready for reading */
              errno = 0;
              svc_getreqset(readfds);
              if( errno == ENETDOWN || errno == ENOTCONN)
              sys$exit( SS$_THIRDPARTY);
       }
