+The

+function terminates the entire process (running \*(TX image), specifying
+the termination status to the operating system. The
+.meta status
+argument is treated exactly like that of the

+function. Unlike that function, this one exits the process immediately,
+cleaning up only low-level operating system resources such as closing file

+cleanup.
