Moves the location of the next read or write operation within a file to a different position.
File reference associated with the file whose file position you want to access.
Distance, in bytes, from the location specified by from to set the file position.
Default: 0
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 position offset 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: start
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
The same reference as refnum.
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)
Web Server: Not supported in VIs that run in a web application
