sesio - enclosure services device driver interface
The ses device driver provides the following ioctls as a
means to access SCSI enclosure services devices.
The ses driver supports the following ioctls:
This ioctl obtains enclosure state in the ses_ioctl
This ioctl is used to set parameters on the enclosure
services device. The ses_ioctl structure is used to
pass information into the driver.
EIO The ses driver was unable to obtain data from the
enclosure services device or the data transfer could
not be completed.
The ses driver does not support the requested ioctl
ENXIO The enclosure services device does not exist.
The user specified a bad data length.
The ses_ioctl structure has the following fields:
uint32_t; /* Size of buffer that follows */
uint8_t page_code: /* Page to be read/written */
uint8_t reserved; /* Reserved; Set to 0 */
unit8t buffer; /* Size arbitrary, user specifies */
Example 1: Using the SES_IOCTL_GETSTATE ioctl
The following example uses the SES_IOCTL_GETSTATE ioctl to
recover 20 bytes of page 4 from a previously opened device.
struct ses_ioctl *sesp;
sesp = (ses_ioctl *)abuf;
sesp->size = 20;
sesp->page_code = 4;
status = ioctl(fd, SES_IOCTL_GETSTATE, abuf);
