- The function <STRONG>setterm</STRONG> is not described in the XSI Curses
- standard and must be considered non-portable. All other
- functions are as described in the XSI curses standard.

<STRONG>setupterm</STRONG> copies the terminal name to the array <STRONG>ttytype</STRONG>.
This is not part of X/Open Curses, but is assumed by some
In System V Release 4, <STRONG>set_curterm</STRONG> has an <STRONG>int</STRONG> return type
and returns <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>. We have chosen to implement the
- XSI Curses semantics.
+ X/Open Curses semantics.
In System V Release 4, the third argument of <STRONG>tputs</STRONG> has the
type <STRONG>int</STRONG> <STRONG>(*putc)(char)</STRONG>.
- The XSI Curses standard prototypes <STRONG>tparm</STRONG> with a fixed num-
- ber of parameters, rather than a variable argument list.
- This implementation uses a variable argument list.
- Portable applications should provide 9 parameters after
- the format; zeroes are fine for this purpose.
-
- XSI notes that after calling <STRONG>mvcur</STRONG>, the curses state may
- not match the actual terminal state, and that an applica-
- tion should touch and refresh the window before resuming
- normal curses calls. Both ncurses and System V Release 4
- curses implement <STRONG>mvcur</STRONG> using the SCREEN data allocated in
- either <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>. So though it is documented as
- a terminfo function, <STRONG>mvcur</STRONG> is really a curses function
- which is not well specified.
-
- XSI states that the old location must be given for <STRONG>mvcur</STRONG>.
- This implementation allows the caller to use -1's for the
- old ordinates. In that case, the old location is unknown.
+ At least one implementation of X/Open Curses (Solaris) re-
+ turns a value other than OK/ERR from <STRONG>tputs</STRONG>. That returns
+ the length of the string, and does no error-checking.
+
+ X/Open Curses prototypes <STRONG>tparm</STRONG> with a fixed number of pa-
+ rameters, rather than a variable argument list. This im-
+ plementation uses a variable argument list, but can be
+ configured to use the fixed-parameter list. Portable ap-
+ plications should provide 9 parameters after the format;
+ zeroes are fine for this purpose.
+
+ In response to comments by Thomas E. Dickey, X/Open Curses
+ Issue 7 proposed the <STRONG>tiparam</STRONG> function in mid-2009.
+
+ X/Open notes that after calling <STRONG>mvcur</STRONG>, the curses state
+ may not match the actual terminal state, and that an ap-
+ plication should touch and refresh the window before re-
+ suming normal curses calls. Both ncurses and System V Re-
+ lease 4 curses implement <STRONG>mvcur</STRONG> using the SCREEN data allo-
+ cated in either <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>. So though it is docu-
+ mented as a terminfo function, <STRONG>mvcur</STRONG> is really a curses
