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.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.

Return values
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/xti.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).
