RMParseSCSIInquiry

This rmcall service builds an SCSI device description and is provided as a convenience for device drivers dealing with SCSI devices. It converts SCSI inquiry data for a device into a device key and a description that can be used in RMCreateDevice.

Syntax

RMParseSCSIInquiry(InquiryData, DescBuffer, DescBufferSize)

Parameters

InquiryData (PVOID) - output

Pointer to a buffer containing SCSI inquiry data for the device.

DescBuffer (PSZ) - input

Pointer to a buffer that will receive the device key and device description built by this service. This data may be used as the device description field (DevDescriptName) of the DEVICESTRUCT used to create the device.

Refer to RMCreateDevice for further information.

DescBufferSize (USHORT) - input

Size of the DescBuffer, in bytes.

Return Code

rc (APIRET) - returns

On systems where the Resource Manager driver is not installed, the library interface code will return RMRC_NOT_INSTALLED.

RMRC_NULL_POINTER : A Resource Manager service received a NULL value for a pointer that was expected to contain a valid 16:16 address.

RMRC_BUFFER_TOO_SMALL : The buffer provided to receive information from a Resource Manager service was too small.

Remarks

RMParseInquiry automatically generates appropriate keys for SCSI devices. An adjunct structure containing the Target/Lun device (ADJ_SCSI_TARGET_LUN) should be passed on the RMCreateDevice service call. See Device Adapter Keys for more information.

Example Code

C

#include <os2.h>
#include <rmcalls.h>

PVOID     InquiryData;
PSZ       DescBuffer;
USHORT    DescBufferSize;
APIRET    rc;

rc = RMParseSCSIInquiry(InquiryData, DescBuffer, DescBufferSize);
