 .SH HISTORY
-SVr4 (1989) implemented these functions under the names
-.BR inswch ,
-.BR winswch ,
-.BR mvinswch ,
-and
-.BR mvwinswch .
+These functions were initially specified by X/Open Curses,
+Issue 4.
+The System\ V Interface Definition,
+Version 4 (1995),
+specified a function named
+.I \%winswch
+(and the usual variants).
+This was a later addition to
+.RI SVr4. x ,
+not appearing in the first SVr4 (1989).
+It differed from X/Open's later
+.I \%wins_wch
+in that it took an argument of type
+.I \%chtype
+instead of
+.IR \%cchar_t "."
