12 DESCRIPTION
13 The ses device driver provides the following ioctls as a means to
14 access SCSI enclosure services devices.
15
16 IOCTLS
17 The ses driver supports the following ioctls:
18
19 SES_IOCTL_GETSTATE
20 This ioctl obtains enclosure state in the
21 ses_ioctl structure.
22
23
24 SES_IOCTL_SETSTATE
25 This ioctl is used to set parameters on the
26 enclosure services device. The ses_ioctl
27 structure is used to pass information into the
28 driver.
29
30
31 ERRORS
32 EIO
33 The ses driver was unable to obtain data from the enclosure
34 services device or the data transfer could not be completed.
35
36
37 ENOTTY
38 The ses driver does not support the requested ioctl
39 function.
40
41
42 ENXIO
43 The enclosure services device does not exist.
44
45
46 EFAULT
47 The user specified a bad data length.
48
49
50 STRUCTURES
51 The ses_ioctl structure has the following fields:
52
53 uint32_t; /* Size of buffer that follows */
54 uint8_t page_code: /* Page to be read/written */
55 uint8_t reserved[3]; /* Reserved; Set to 0 */
56 unit8t buffer[1]; /* Size arbitrary, user specifies */
57
58
59 EXAMPLES
60 Example 1 Using the SES_IOCTL_GETSTATE ioctl
61
62
63 The following example uses the SES_IOCTL_GETSTATE ioctl to recover 20
64 bytes of page 4 from a previously opened device.
65
66
67 char abuf[30];
68 struct ses_ioctl *sesp;
69 int status;
70 sesp = (ses_ioctl *)abuf;
71 sesp->size = 20;
72 sesp->page_code = 4;
73 status = ioctl(fd, SES_IOCTL_GETSTATE, abuf);
