.SH RETURN VALUE
Routines that return an integer return \fBERR\fR upon failure and an
integer value other than \fBERR\fR upon successful completion, unless
\fBgetmaxyx\fR are undefined (i.e., these should not be used as the
right-hand side of assignment statements).
.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+Most \*(``mv\*(''-prefixed functions
+(except variadic functions such as \fBmvprintw\fP)
+are provided both as macros and functions.

Routines that return pointers return \fBNULL\fR on error.

+\-\-with\-termlib
+Low-level functions which do not depend upon whether the library
+supports wide-characters, are provided in the tinfo library.
+.IP
+By doing this, it is possible to share the tinfo library between
+wide/normal configurations as well as reduce the size of the library
+when only low-level functions are needed.

+.TP 5
\-\-with\-trace
The \fBtrace\fP function normally resides in the debug library,
but it is sometimes useful to configure this in the shared library.
If the header is included, its symbols may be made visible.
That depends on the value used for \fB_XOPEN_SOURCE\fP
feature test macro.
+.bP
+X/Open Curses documents one required header,
+in a special case: <stdarg.h> before <curses.h> to prototype
+the \fBvw_printw\fP and \fBvw_scanw\fP functions
+(as well as the obsolete
+the \fBvwprintw\fP and \fBvwscanw\fP functions).
+Each of those uses a \fBva_list\fP parameter.
+.IP
+The two obsolete functions were introduced in SVr3.
+The other functions were introduced in X/Open Curses.
+In between, SVr4 curses provided for the possibility that
+an application might include either <varargs.h> or <stdarg.h>.
+Initially, that was done by using \fBvoid*\fP for the \fBva_list\fP
+parameter.
+Later, a special type (defined in <stdio.h>) was introduced,
+to allow for compiler type-checking.
+That special type is always available,
+because <stdio.h> is always included by <curses.h>.
+.IP
+None of the X/Open Curses implementations require an application
+to include <stdarg.h> before <curses.h> because they either
+have allowed for a special type, or (like ncurses) include <stdarg.h>
+directly to provide a portable interface.
