timod(7)timod(7)NAMEtimod - Transport Interface cooperating STREAMS module
DESCRIPTIONtimod 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.ic_cmd = cmd;
strioctl.ic_timeout = INFTIM;
strioctl.ic_len = size;
strioctl.ic_dp = (char *)buf
ioctl(fildes, I_STR, &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:
TI_BIND Bind an address to the underlying transport protocol
provider. The message issued to the TI_BIND ioctl is
equivalent to the TI message type T_BIND_REQ and the
message returned by the successful completion of the ioctl
is equivalent to the TI message type T_BIND_ACK.
TI_UNBIND Unbind an address from the underlying transport protocol
provider. The message issued to the TI_UNBIND ioctl is
equivalent to the TI message type T_UNBIND_REQ and the
message returned by the successful completion of the ioctl
is equivalent to the TI message type T_OK_ACK.

TI_GETINFO Get the TI protocol specific information from the
transport protocol provider. The message issued to the
TI_GETINFO ioctl is equivalent to the TI message type
T_INFO_REQ and the message
returned by the successful completion of the ioctl is
equivalent to the TI message type T_INFO_ACK.
TI_OPTMGMT Get, set or negotiate protocol specific options with the
transport protocol provider. The message issued to the
TI_OPTMGMT ioctl is equivalent to the TI message type
T_OPTMGMT_REQ and the message returned by the successful
completion of the ioctl is equivalent to the TI message
type T_OPTMGMT_ACK.

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)].
