+.Ft int
+.Fn truncate "const char *path" "off_t length"

+.Sh DESCRIPTION
+.Fn truncate
+causes the file named by
+.Fa path
+or referenced by
+.Fa fd
+to have a size of
+.Fa length
+bytes.
+If the file previously was larger than this size, the extra data is discarded.
+If it was previously shorter than
+.Fa length ,
+its size is increased to the specified value and
+the extended area appears as if it were zero-filled.
+.Pp
+With
+.Fn ftruncate ,
+the file must be open for writing; for
+.Fn truncate ,
+the process must have write permissions for the file.
+.Sh RETURN VALUES
+A value of 0 is returned if the call succeeds.
+If the call fails a \-1 is returned, and the global variable
+.Va errno
+specifies the error.

+.St -p1003.1-2004
