  30   Description:
  31         These routines read a chtype or cchar_t string from the window,
  32         starting at the current or specified position, and ending at the
  33         right margin, or after n elements, whichever is less.
  34
  35   Return Value:
  36         All functions return the number of elements read, or ERR on
  37         error.
