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 (see Streams Primer) 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.

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)).
