+Waits for and returns the status code of the child process. The
+status code encodes both the return code of the process and
+information about whether it exited using the \cfunction{exit()}
+system call or died due to a signal. Functions to help interpret the
+status code are defined in the \refmodule{os} module; see section
+\ref{os-process} for the \function{W\var{*}()} family of functions.
