+
+In some situations it is useful to explicitly determine the size of a

+The @code{truncation} function truncates the file named by @var{name} to
+at most @var{length} bytes. I.e., if the file was larger before the
+extra bytes are stripped of. If the file was small or equal to
+@var{length} in size before nothing is done. The file must be writable
+by the user to perform this operation.
+
+The return value is zero is everything wnet ok. Otherwise the return
+value is @math{-1} and the global variable @var{errno} is set to:

+@deftypefun int ftruncate (int @var{fd}, size_t @var{length})
+The @code{ftruncate} function is similar to the @code{truncate}
+function. The main difference is that it takes a descriptor for an
+opened file instead of a file name to identify the object. The file
+must be opened for writing to successfully carry out the operation.
+
+The POSIX standard leaves it implementation defined what happens if the
+specified new @var{length} of the file is bigger than the original size.
+The @code{ftruncate} function might simply leave the file alone and do
+nothing or it can increase the size to the desired size. In this later
+case the extended area should be zero-filled. So using @code{ftruncate}
+is no reliable way to increase the file size but if it is possible it is
+probably the fastest way. The function also operates on POSIX shared
+memory segments if these are implemented by the system.
+
