SunOS 5.5 STREAMS Modules timod(7M)
NAME timod − Transport Interface cooperating STREAMS module
SYNOPSIS #include <sys/stropts.h>
ioctl(fildes, I_STR, &my_strioctl);
DESCRIPTION timod is a STREAMS module for use with the Transport Interface (TI) functions of the Net-
work Services library. The timod module converts a set of ioctl(2) calls into STREAMS
messages that may be consumed by a transport protocol provider that supports the Tran-
sport Interface. This allows a user to initiate certainTI functions as atomic operations.
The timod module must be pushed onto only a stream terminated by a transport protocol
provider that 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 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 my_strioctl;
-
-
strioctl.ic_cmd = cmd;
strioctl.ic_timout = INFTIM;
strioctl.ic_len = size;
strioctl.ic_dp = (char ∗)buf
ioctl(fildes, I_STR, &my_strioctl);
On issuance, size is the size of the appropriate TI message to be sent to the transport pro-
vider and on return size is the size of the appropriate TI message from the transport pro-
vider in response to the issued TI message. buf is a pointer to a buffer large enoughto
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 underlyingtransport protocol provider. The
message issued to the TI_BIND ioctl is equivalent to theTI message
type T_BIND_REQ and the message returned by the successful comple-
tion 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 theTI mes-
sage type T_UNBIND_REQ and the message returned by the successful
completion of the ioctl is equivalent to theTI message type T_OK_ACK.
TI_GETINFO Get the TI protocol specific information from the transport protocol pro-
vider. The message issued to the TI_GETINFO ioctl is equivalent to the
TI message type T_INFO_REQ and the message returned by the
