IOCTL_MINIPORT_SIGNATURE_ENDURANCE_INFO SIGNATURE

Description

IOCTL_MINIPORT_SIGNATURE_ENDURANCE_INFO is the system-defined signature used in conjunction with the IOCTL_SCSI_MINIPORT control code to request that a miniport return a target device's endurance information.

Parameters

Major code

Input buffer

See Remarks.

Input buffer length

See Remarks.

Output buffer

See Remarks.

Output buffer length

See Remarks.

Input/output buffer

None.

Input/output buffer length

Not applicable.

Status block

Not applicable.

Remarks

For this signature, IOCTL_SCSI_MINIPORT's input buffer will contain an SRB_IO_CONTROL structure with:

• The Signature member is set to IOCTL_MINIPORT_SIGNATURE_ENDURANCE_INFO.

• The ControlCode member is set to IOCTL_STORAGE_QUERY_PROPERTY.

If the miniport recognizes and supports the IOCTL_MINIPORT_SIGNATURE_ENDURANCE_INFO signature, it should return its device's endurance data in a STORAGE_ENDURANCE_DATA_DESCRIPTOR structure. Specifically, IOCTL_SCSI_MINIPORT's output buffer will contain an SRB_IO_CONTROL structure, followed immediately by a STORAGE_ENDURANCE_DATA_DESCRIPTOR structure that contains the endurance data.

See IOCTL_SCSI_MINIPORT for information on how to calculate buffer sizes.
