filename = an input string that specifies the file to which logging data will be recorded. The format may be simply a
file name (“ex1629_log”) or an absolute path (“C:\vxipnp\vtex1629\ex1629_log.txt”). If a file name (relative path)
is provided, the file will be created in the current working directory of the application.
append = a Boolean input value that specifies if log results will be appended to an existing file. A value of
VI_TRUE will cause logged information to be appended to an existing file. Otherwise, any previous data will be
overwritten.
