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)].
