 NAME
removable-media - removable media device property
 DESCRIPTION

A device that supports removable media\(emsuch as CDROM, JAZZ, and ZIP
drives\(emand that supports power management and expects automatic mounting of
the device via the volume manager should export the boolean (zero length)
property removable-media. This property enables the system to make the
power state of the device dependent on the power state of the frame buffer and
monitor. See the power.conf(4) discussion of the
device-dependency-property entry for more information.

Devices that behave like removable devices (such as PC ATA cards, where
the controller and media both are removed at the same time) should also export
this property.
 EXAMPLES

Example 1 removable-media Entry

An example of a removable-media entry from the .conf file of a
driver is shown below.

# This entry keeps removable media from being powered down unless
# the console framebuffer and monitor are powered down
#
removable-media=1;


Example 2 Implementation in attach()

Below is an example of how the entry above would be implemented in the
attach(9E) function of the driver.

xxattach(dev_info_t *dip, ddi_attach_cmd_t cmd)
 {
 ...
 if (ddi_prop_create(DDI_DEV_T_NONE, dip, DDI_PROP_CANSLEEP,
 "removable-media", NULL, 0)) != DDI_PROP_SUCCESS)
 goto failed;
 ...
 }
