     TFTP(2)                                                   TFTP(2)

     NAME
          tftp - Trivial File Transfer Protocol

     SYNOPSIS
          tftp := load Tftp Tftp->PATH;
          Tftp: module
          {
             init:    fn(progress: int);
             receive: fn(host: string, filename: string,
                         fd: ref Sys->FD): string;
          };

     DESCRIPTION
          Tftp fetches files from an Internet TFTP server.  It is typ-
          ically used only to fetch kernels or configuration files
          when booting.  Only one transfer can be active at any given
          time.

          Init must be called once before using any other function of
          the module.  If progress is non-zero, receive will periodi-
          cally print a character as blocks are received: `.'  for
          every 25 blocks, `S' for a sequence error, `T' for a time-
          out.

          Receive attempts to fetch the contents of filename from host
          and writes the blocks of data to fd as they are received.
          It returns when the file transfer has completed, returning a
          nil string on success or a diagnostic string otherwise.
          When booting, fd is typically open on the kexec file of
          boot(3).
