VMS Help CC, Run-time functions, wait  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Checks the status of the child process before exiting.  A child
  process is terminated when the parent process terminates.  This
  function is nonreentrant.

  Syntax:

       #include <wait.h>

       pid_t wait(int *status);
