GetTapePosition info  Overview  Group

The GetTapePosition function retrieves the current address of the tape, in logical or absolute blocks.

DWORD GetTapePosition(

    HANDLE hDevice,

// handle of open device

    DWORD dwPositionType,

// type of address to obtain

    LPDWORD lpdwPartition,

// address of current tape partition

    LPDWORD lpdwOffsetLow,

// address of low-order 32 bits of tape position

    LPDWORD lpdwOffsetHigh 

// address of high-order 32 bits of tape position



Identifies the device on which to get the tape position. This handle is created by using CreateFile.
Specifies the type of address to obtain. This parameter can be one of the following values:




The lpdwOffsetLow and lpdwOffsetHigh parameters receive the device-specific block address. The dwPartition parameter receives zero.


The lpdwOffsetLow and lpdwOffsetHigh parameters receive the logical block address. The dwPartition parameter receives the logical tape partition.

Points to a variable that receives the number of the current tape partition. Partitions are numbered logically from 1 through n, where 1 is the first partition on the tape and n is the last. When a device-specific block address is retrieved, or if the device supports only one partition, this parameter receives zero.
Points to a variable that receives the low-order 32 bits of the current tape position.
Points to a variable that receives the high-order 32 bits of the current tape position. This parameter can be NULL if the high-order 32 bits are not required.

Return Values

If the function succeeds, the return value is NO_ERROR.

If the function fails, the return value is one of the following error codes:

Error code



An attempt to access data before the beginning-of-medium marker failed.


A reset condition was detected on the bus.


The end-of-tape marker was reached during an operation.


A filemark was reached during an operation.


A setmark was reached during an operation.


The end-of-data marker was reached during an operation.


The tape could not be partitioned.


The block size is incorrect on a new tape in a multivolume partition.


The partition information could not be found when a tape was being loaded.


The tape that was in the drive has been replaced or removed.


There is no media in the drive.


The tape driver does not support a requested function.


An attempt to lock the ejection mechanism failed.


An attempt to unload the tape failed.


The media is write protected.


A logical block address is relative to a partition. The first logical block address on each partition is zero.

Call the GetTapeParameters function to obtain information about the status, capabilities, and capacities of tape drives and media.
