- enclosure services device driver interface
SYNOPSIS #include <sys/scsi/targets/sesio.h>
device driver provides the following ioctls as a means to access
SCSI enclosure services devices.
driver supports the following ioctls:
SES_IOCTL_GETSTATE This ioctl obtains enclosure state in the ses_ioctl
SES_IOCTL_SETSTATE This ioctl is used to set parameters on the enclosure
services device. The ses_ioctl
structure is used to
pass information into the driver.
EXAMPLES 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);
EIO The ses
driver was unable to obtain data from the enclosure
services device or the data transfer could not be completed.
ENOTTY The ses
driver does not support the requested ioctl function.
ENXIO The enclosure services device does not exist.
EFAULT The user specified a bad data length.
structure has the following fields:
uint32_t page_size; /* Size of buffer that follows */
uint8_t page_code: /* Page to be read/written */
uint8_t reserved; /* Reserved; Set to 0 */
