These functions are described in the XSI Curses standard, Issue 4. It
specifies that portable applications must not call \fBinitscr\fR more than
once.
+
+Old versions of curses, e.g., BSD 4.4, may have returned a null pointer
+from \fBinitscr\fR when an error is detected, rather than exiting.
+It is safe but redundant to check the return value of \fBinitscr\fR
+in XSI Curses.
