Ioctl Requestssesio(7I)

NAME

 sesio - enclosure services device driver interface

SYNOPSIS

  
#include<sys/sesio.h>

DESCRIPTION

 

The ses device driver provides the following ioctls as a means to access SCSI enclosure services devices.

IOCTLS

 

The ses driver supports the following ioctls:

SES_IOCTL_GETSTATE
This ioctl obtains enclosure state in the ses_ioctl structure.
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.

ERRORS

 
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.

STRUCTURES

 

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[3];    /* Reserved; Set to 0 */
unit8t  buffer[1];      /* Size arbitrary, user specifies */

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.

  
char   abuf[30];
struct ses_ioctl *sesp;
int    status;
sesp = (ses_ioctl *)abuf;
sesp->size = 20;
sesp->page_code = 4;
status = ioctl(fd, SES_IOCTL_GETSTATE, abuf);
