Advanced File IO: Text Files, Binary Data files, and Configuration Files Youve currently noticed from Section 9, Exploring Guitar strings and Document IO, the most common file IO functions LabVIEW offers to provide. You will today find out how to work on data files by research, performing a sequence of procedure and introspection steps, instead than basically reading or composing the document in one fell swoop. This will permit you to achieve some even more complicated and high-performance use cases. Opening and Closing File Sources A file is a set of purchased bytes on your computer disksimilar to the method a thread can be a place of ordered heroes or an range can be a set of ordered elements. Because documents can become very big, it is certainly often desired to not learn the whole material of a file into storage all at as soon as, but instead, only go through small portions of it (maybe one line at a period) and perform operations structured on the data that can be read. Many of the functions for composing and reading data to and from files use a refnum (brief for reference amount) as a deal with to a file that offers been opened up for writing or reading through. By handle, we indicate that we are not moving around the data of the document, but rather, something that pertains to the open up file. You can believe of a file refnum like a path to an open fileit will be not really the data of the file, but something that helps us know where to discover the data. The file read and compose features in LabVIEW are usually polymorphic. You can use them with either document path inputs OR document refnum inputs. To open up a refnum to a document, we use the OpenCreateReplace Document functionality (observe Physique 14.6). The refnum will end up being transferred out via thé refnum out port. When we are usually done creating or reading through the file, we will move the file refnum to the Close File functionality (see Amount 14.7), to inform LabVIEW that we no more time need accessibility to the file. OpenCreateReplace File Amount 14.7. Close Document Today that we understand how to open up and close up a document, lets take a look at how to write and learn data. Advanced Document Functions Sometimes youll want to perform specific file tasks, like as create web directories, modify the permissions on a particular file, or remove a document. Advanced File Functions colour scheme We wont cover up every one of these features in this part, but properly talk about a few of them following. File Position The document marker will be a number that shows us the byte offset where you are usually currently operating in a document. The finish of file is definitely the balance prior (simply beyond) the final byte in the document (signifying the end of the file)the end of file is furthermore the document size. When you first open up a file, the document marker is certainly established to an initial worth of 0, and as you compose or go through to the file, the marker is moved forwards each time by the number of bytes composed or read through. The file marker assists you by keeping track of where you are usually in the filethere is definitely no want for you to clearly designate the position where you want to compose or study data (although you can stipulate the placement to examine or create, if you wish). Generally, you will begin at the starting of a file and keep writing or reading through data contiguously until you reach the finish of the filethis can be typically known to as sequential entry, as compared to arbitrary gain access to (clearly indicating the position of each réad and write procedure).
