<H2>FGETLINE Read a String from a File
</H2>
<P>
Section: <A HREF=sec_io.html> Input/Ouput Functions </A>
<H3>Usage</H3>
Reads a string from a file. The general syntax for its use
is
<PRE>
s = fgetline(handle)
</PRE>
<P>
This function reads characters from the file <code>handle</code> into
a <code>string</code> array <code>s</code> until it encounters the end of the file
or a newline. The newline, if any, is retained in the output
string. If the file is at its end, (i.e., that <code>feof</code> would
return true on this handle), <code>fgetline</code> returns an empty
string.
<H3>Example</H3>
First we write a couple of strings to a test file.
<PRE>
--> fp = fopen('testtext','w');
--> fprintf(fp,'String 1\n');
--> fprintf(fp,'String 2\n');
--> fclose(fp);
</PRE>
<P>
Next, we read then back.
<PRE>
--> fp = fopen('testtext','r')
fp =
10
--> fgetline(fp)
ans =
String 1
--> fgetline(fp)
ans =
String 2
--> fclose(fp);
</PRE>
