 NAME    [Toc]    [Back]
      timod - STREAMS module for converting ioctl() calls into Transport
      Interface messages

 DESCRIPTION    [Toc]    [Back]
      The timod module is a STREAMS module that converts ioctl() calls from
      a transport user supporting the Transport Interface (TI) into messages
      that a transport protocol provider supporting TI can consume.  This
      allows the user to initiate certain TI functions as atomic operations.
      This release of HP-UX no longer automatically pushes timod whenever a
      t_open(3) is performed.  The TLI and XTI libraries have been modified
      to no longer require this module to perform the atomic operations
      described within this man page.  Binary compatibility is not a problem
      since the module will still exist within the kernel.  But, any
      application which is recompiled and expects the module to be
      automatically pushed, may not work without code modification.

      The user places and removes the timod module on a device stream by
      calling the STREAMS I_PUSH ioctl() and I_POP ioctl() functions.  (The
      TLI function t_open() pushes timod onto the device stream for the
      user.)  The timod module should only be pushed onto streams which are
      terminated by transport providers which conform to the Transport
      Interface.  tirdwr(7) is an alternative interface to timod which
      supports the read() and write() system calls.  If tirdwr has been
      pushed onto the stream, the user should use the I_POP ioctl to remove
      the tirdwr module from the stream before pushing timod.

      The timod module transparently passes any STREAMS messages that are
      not generated by the ioctl() commands described below to the
      neighboring module or driver.  timod will act on an I_STR ioctl()
      whose strioctl.ic_cmd field is one of the values below.  (See
      streamio(7) for a description of the I_STR ioctl and the strioctl
      structure.)

      TI_BIND        This TI command binds an address to the transport
                     protocol provider.  The STREAMS message that the module
                     issues to the TI_BIND ioctl() call is equivalent to the
                     TI message type T_bind_req.  The STREAMS message that
                     the module returns in response to the successful
                     completion of the TI_BIND ioctl() call is equivalent to
                     the TI message type T_bind_ack.

      TI_UNBIND      This TI command unbinds an address from the transport
                     protocol provider.  The STREAMS message that the module
                     issues to the TI_UNBIND ioctl() call is equivalent to
                     the TI message type T_unbind_req.  The STREAMS message
                     that the module returns in response to the successful
                     completion of the TI_UNBIND ioctl() call is equivalent
                     to the TI message type T_ok_ack.

      TI_GETINFO     This TI command gets the TI protocol-specific
                     information from the transport protocol provider.  The
                     STREAMS message that the module issues to the
                     TI_GETINFO ioctl() call is equivalent to the TI message
                     type T_info_req.  The STREAMS message that the module
                     returns in response to the successful completion of the
                     TI_GETINFO ioctl() call is equivalent to the TI message
                     type T_info_ack.

      TI_OPTMGMT     This TI command gets, sets, or negotiates TI protocolspecific
 options with the transport protocol provider.
                     The STREAMS message that the module issues to the
                     TI_OPTMGMT ioctl() call is equivalent to the TI message
                     type T_optmgmt_req.  The STREAMS message that the
                     module returns in response to the successful completion
                     of the TI_OPTMGMT ioctl() call is equivalent to the TI
                     message type T_optmgmt_ack.

 RETURN VALUES    [Toc]    [Back]
      If the timod module returns an error for an ioctl() call, the lower 8
      bits of the return value will be one of the TI error codes defined in
      the <tiuser.h> header file.  If the TI error is of the type TSYERR,
      then the second 8 bits of the return value will contain an error as
      defined in the <errno.h> header file.  The STREAMS message that the
      module issues when an ioctl() call results in an error is equivalent
      to the TI message type T_error_ack.

 FILES    [Toc]    [Back]
      <xti.h>        defines the error codes for XTI functions.

      <tiuser.h>     defines the error codes for TI functions.

      <tihdr.h>      defines the message types for TI functions.

      <errno.h>      defines the error codes for system errors.
