refnum

File reference associated with the file whose file position you want to access.

datatype_icon

offset

Distance, in bytes, from the location specified by from to set the file position.

Default: 0

datatype_icon

from

Pre-defined location in the file to which you can move the file position. Use this location in combination with offset to specify an exact file position.

Name Description
start

Sets the file position offset bytes from the beginning of the file. If from is 0, wire a value greater than or equal to 0 to offset.

end

Sets the file positionoffset bytes from the end of the file. If from is 1, wire a value less than or equal to 0 to offset.

current

Sets the file position offset bytes from the current file position.

Default:

You wired a value to offset. start
You did not wire a value to offset. current file position

datatype_icon

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error

datatype_icon

refnum out

The same reference as refnum.

datatype_icon

error out

Error information. The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: All devices (only within an Optimized FPGA VI)
