How can a file be truncated on System V??

[Cs411s03]

The Xenix function chsize(S) can be found in /lib/libx.a under System V 3.2.
It functions similarly to the BSD ftruncate() function:

	int chsize(fildes, size)
	int fildes;
	long size;

The chsize function will change the file associated with fildes to be
exactly size bytes in length ...
