<h3>Name</h3>

						|
fstat - get file state information
 | 
						|
</p>
 | 
						|

<h3>Library</h3>

Standard C Library (libc, -lc)

<h3>Synopsis</h3>
 | 
						|
<p>
 | 
						|
<tt>#include <sys/stat.h></tt><br>
 | 
						|
<br>
 | 
						|
<tt>int</tt><br>
 | 
						|
<tt>fstat(int </tt><em>fd</em><tt>,
 | 
						|
struct stat *</tt><em>statbuf</em><tt>);</tt>
 | 
						|
</p>
 | 
						|
 | 
						|
<h3>Description</h3>
 | 
						|
<p>
 | 
						|
<tt>fstat</tt> retrieves status information about the file referred to
 | 
						|
by the file handle <em>fd</em> and stores it in the stat structure
 | 
						|
pointed to by <em>statbuf</em>.
 | 
						|
</p>
 | 
						|
 | 
						|
<p>
 | 
						|
The call (like all system calls) should be atomic; that is, the
 | 
						|
information retrieved should come from a single point in time.
 | 
						|
</p>
 | 
						|
 | 
						|
<h3>Return Values</h3>
 | 
						|
<p>
 | 
						|
On success, <tt>fstat</tt> returns 0. On error, -1 is returned, and <A
 | 
						|
HREF=errno.html>errno</A> is set according to the error encountered.
 | 
						|
</p>
 | 
						|
 | 
						|
