◆ autodetect_open()

smart_device * os_linux::linux_megaraid_device::autodetect_open ( )

overridevirtual

Open device with autodetection support.

May return another device for further access. In this case, the original pointer is no longer valid. Default implementation calls 'open()' and returns 'this'.

Reimplemented from smart_device.

Definition at line 1116 of file os_linux.cpp.

◆ close()

bool os_linux::linux_megaraid_device::close ( )

overridevirtual

Close device, return false on error.

Reimplemented from os_linux::linux_smart_device.

◆ scsi_pass_through()

bool os_linux::linux_megaraid_device::scsi_pass_through ( scsi_cmnd_io * iop )

overridevirtual

SCSI pass through.

Returns false on error.

Implements scsi_device.
