Syntax

a = fgets(fid)

a = fgets(fid, n)

Description

Reads a specified number of characters or a line from a file. fgets(fid) reads a line from the file you specify in fid. fgets(fid, n) reads n characters from the file you specify in fid. If the file mark reaches an end-of-line character, LabVIEW stops reading from the file. To read a line or a specified number of characters from a byte stream file, you must use this function.

Examples
