NAME
      timod - Transport Interface cooperating STREAMS module

DESCRIPTION
      timod is a STREAMS module for use with the Transport Interface (TI)
      functions of the Network Services library.  The timod module converts a
      set of ioctl(2) calls into STREAMS messages that may be consumed by a
      transport protocol provider which supports the Transport Interface.  This
      allows a user to initiate certain TI functions as atomic operations.

      The timod module must be pushed onto only a stream terminated by a
      transport protocol provider which supports the TI.

      All STREAMS messages, with the exception of the message types generated
      from the ioctl commands described below, will be transparently passed to
      the neighboring STREAMS module or driver.  The messages generated from
      the following ioctl commands are recognized and processed by the timod
      module.  The format of the ioctl call is:

           #include <sys/stropts.h>
                       -
                       -
           struct strioctl strioctl;
                       -
                       -
           strioctl.iccmd = cmd;
           strioctl.ictimeout = INFTIM;
           strioctl.iclen = size;
           strioctl.icdp = (char *)buf
           ioctl(fildes, ISTR, &strioctl);

      Where, on issuance, size is the size of the appropriate TI message to be
      sent to the transport provider and on return size is the size of the
      appropriate TI message from the transport provider in response to the
      issued TI message.  buf is a pointer to a buffer large enough to hold the
      contents of the appropriate TI messages.  The TI message types are
      defined in <sys/tihdr.h>.  The possible values for the cmd field are:

      TIBIND        Bind an address to the underlying transport protocol
                     provider.  The message issued to the TIBIND ioctl is
                     equivalent to the TI message type TBINDREQ and the
                     message returned by the successful completion of the ioctl
                     is equivalent to the TI message type TBINDACK.

      TIUNBIND      Unbind an address from the underlying transport protocol
                     provider.  The message issued to the TIUNBIND ioctl is
                     equivalent to the TI message type TUNBINDREQ and the
                     message returned by the successful completion of the ioctl
                     is equivalent to the TI message type TOKACK.

      TIGETINFO     Get the TI protocol specific information from the
                     transport protocol provider.  The message issued to the
                     TIGETINFO ioctl is equivalent to the TI message type
                     TINFOREQ and the message
                     returned by the successful completion of the ioctl is
                     equivalent to the TI message type TINFOACK.

      TIOPTMGMT     Get, set or negotiate protocol specific options with the
                     transport protocol provider.  The message issued to the
                     TIOPTMGMT ioctl is equivalent to the TI message type
                     TOPTMGMTREQ and the message returned by the successful
                     completion of the ioctl is equivalent to the TI message
                     type TOPTMGMTACK.

DIAGNOSTICS
      If the ioctl system call returns with a value greater than 0, the lower 8
      bits of the return value will be one of the TI error codes as defined in
      <sys/tiuser.h>.  If the TI error is of type TSYSERR, then the next 8 bits
      of the return value will contain an error as defined in <sys/errno.h>
      [see intro(2)].
