NAME

  timod - STREAMS module for converting ioctl() calls into TI messages


DESCRIPTION

  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 TI functions as atomic operations.

  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 timod module recognizes and processes STREAMS messages generated by
  I_STR ioctl() calls containing the following TI commands:

  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 TI_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 TI_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 TI_INFO_ACK.

  TI_OPTMGMT
      This TI command gets, sets, or negotiates TI protocol-specific 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 TI_OPTMGMT_ACK.

  The timod module transparently passes any STREAMS messages that are not
  generated by the ioctl() calls previously described to the neighboring
  module or driver.

  RETURN VALUES

  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
  sys/tiusr.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
  sys/errno.h header file.
