16 timod is a STREAMS module for use with the Transport Interface ("TI")
17 functions of the Network Services library. The timod module converts a
18 set of ioctl(2) calls into STREAMS messages that may be consumed by a
19 transport protocol provider that supports the Transport Interface. This
20 allows a user to initiate certain TI functions as atomic operations.
21 The timod module must be pushed onto only a stream terminated by a
24 transport protocol provider that supports the TI.
25 All STREAMS messages, with the exception of the message types generated
28 from the ioctl commands described below, will be transparently passed
29 to the neighboring module or driver. The messages generated from the
30 following ioctl commands are recognized and processed by the timod mod‐
31 ule. The format of the ioctl call is:
32 #include <sys/stropts.h>
34 -
35 -
36 struct strioctl my_strioctl;
37 -
38 -
39 strioctl.ic_cmd = cmd;
40 strioctl.ic_timout = INFTIM;
41 strioctl.ic_len = size;
42 strioctl.ic_dp = (char *)buf
43 ioctl(fildes, I_STR, &my_strioctl);
44 On issuance, size is the size of the appropriate TI message to be sent
48 to the transport provider and on return size is the size of the appro‐
49 priate TI message from the transport provider in response to the issued
50 TI message. buf is a pointer to a buffer large enough to hold the con‐
51 tents of the appropriate TI messages. The TI message types are defined
52 in <sys/tihdr.h>. The possible values for the cmd field are:
53 TI_BIND Bind an address to the underlying transport protocol
55 provider. The message issued to the TI_BIND ioctl is
56 equivalent to the TI message type T_BIND_REQ and the
57 message returned by the successful completion of the
58 ioctl is equivalent to the TI message type T_BIND_ACK.
59 TI_UNBIND Unbind an address from the underlying transport protocol
62 provider. The message issued to the TI_UNBIND ioctl is
63 equivalent to the TI message type T_UNBIND_REQ and the
64 message returned by the successful completion of the
65 ioctl is equivalent to the TI message type T_OK_ACK.
66 TI_GETINFO Get the TI protocol specific information from the trans‐
69 port protocol provider. The message issued to the
70 TI_GETINFO ioctl is equivalent to the TI message type
71 T_INFO_REQ and the message returned by the successful
72 completion of the ioctl is equivalent to the TI message
73 type T_INFO_ACK.
74 TI_OPTMGMT Get, set, or negotiate protocol specific options with
77 the transport protocol provider. The message issued to
78 the TI_OPTMGMT ioctl is equivalent to the TI message
79 type T_OPTMGMT_REQ and the message returned by the suc‐
80 cessful completion of the ioctl is equivalent to the TI
81 message type T_OPTMGMT_ACK.

104 If the ioctl returns with a value greater than 0, the lower 8 bits of
105 the return value will be one of the TI error codes as defined in
106 <sys/tiuser.h>. If the TI error is of type TSYSERR, then the next 8
107 bits of the return value will contain an error as defined in
108 <sys/errno.h> (see Intro(3)).
