Detailed Description

This struct contains the parameters for BlockPermalock Access Operation.

Field Documentation

◆ memoryBank

MEMORY_BANK BLOCK_PERMALOCK_ACCESS_PARAMS::memoryBank

Memory bank on which access operation is to be performed.

◆ readLock

BOOLEAN BLOCK_PERMALOCK_ACCESS_PARAMS::readLock

ReadLock specifies whether a tag backscatters the perlock status of, or permalocks, one of more blocks within the memory bank as specified.

when readLock is true, it performs block perma lock in specified memory bank starting at offset. When readLock is false, the Reader get the permalock mask.

◆ byteOffset

UINT16 BLOCK_PERMALOCK_ACCESS_PARAMS::byteOffset

Byte offset; Address of the first byte for the Mask.

◆ byteCount

UINT16 BLOCK_PERMALOCK_ACCESS_PARAMS::byteCount

Specifies the range of Mask, starting from byteOffset and ending (16xBlockRange)-1 blocks later.

This is valid only when readLock is false. i.e. for read operation

◆ accessPassword

UINT32 BLOCK_PERMALOCK_ACCESS_PARAMS::accessPassword

Password to be used for the Access operation.

◆ pMask

UINT8* BLOCK_PERMALOCK_ACCESS_PARAMS::pMask

Mask specifies which memory blocks a tag permalocks.

Masks depends on the readLock as follows: When readLock is false, the Reader omits permalock mask.
when readLock is true, the Reader should permalock as specified by the Mask. The application should allocate an UINT8 array and assign it to this field. The Mask to be used for bit-wise comparison should be filled in the array.

◆ maskLength

UINT16 BLOCK_PERMALOCK_ACCESS_PARAMS::maskLength

Number of bytes in pMask to be taken for comparison.

◆ lpReserved

LPVOID BLOCK_PERMALOCK_ACCESS_PARAMS::lpReserved[4]

Reserved for future.
