+ document in manpages that "mv" functions first use wmove() to check the window pointer and whether the position lies within the window (suggested by Poul-Henning Kamp). + fixes to curs_color.3x, curs_kernel.3x and wresize.3x manpages (patch by Tim van der Molen). + modify configure script to transform library names for tic- and tinfo-libraries so that those build properly with Mac OS X shared library configuration. + modify configure script to ensure that it removes conftest.dSYM directory leftover on checks with Mac OS X. + modify configure script to cleanup after check for symbolic links.

.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
\fBadd_wch\fP,
|
|
\fBwadd_wch\fP,
|
|
\fBmvadd_wch\fP, and
|
|
\fBmvwadd_wch\fP
|
|
functions put the complex character \fIwch\fP into the given
|
|
window at its current position,
|
|
which is then advanced.
|
|
These functions perform
|
|
wrapping and special-character processing as follows:
|
|
.TP 5
|
|
\-
|
|
If \fIwch\fP refers to a spacing character,
|
|
then any previous character at that location is removed.
|
|
A new character specified by \fIwch\fP is
|
|
placed at that location with rendition specified by \fIwch\fP.
|
|
The cursor then advances to
|
|
the next spacing character on the screen.
|
|
.TP 5
|
|
\-
|
|
If \fIwch\fP refers to a non-spacing character,
|
|
all previous characters at that location are preserved.
|
|
The non-spacing characters of \fIwch\fP
|
|
are added to the spacing complex character,
|
|
and the rendition specified by \fIwch\fP is ignored.
|
|
.TP 5
|
|
\-
|
|
If the character part of \fIwch\fP is
|
|
a tab, newline, backspace or other control character,
|
|
the window is updated and the cursor moves as if \fBaddch\fR were called.
|
|
.PP
|
|
The \fBecho_wchar\fP
|
|
function is functionally equivalent to a call to
|
|
\fBadd_wch\fP
|
|
followed by a call to
|
|
\fBrefresh\fP.
|
|
Similarly, the
|
|
\fBwecho_wchar\fP
|
|
is functionally equivalent to a call to
|
|
\fBwadd_wch\fP
|
|
followed by a call to
|
|
\fBwrefresh\fP.
|
|
The knowledge
|
|
that only a single character is being output is taken into consideration and,
|
|
for non-control characters, a considerable performance gain might be seen
|
|
by using the *\fBecho\fP* functions instead of their equivalents.
|
|
.SH RETURN VALUES
|
|
.PP
|
|
All routines return the integer \fBERR\fR upon failure and \fBOK\fR on success.
|
|
.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.
|
|
.SH NOTES
|
|
.PP
|
|
Note that
|
|
\fBadd_wch\fP,
|
|
\fBmvadd_wch\fP,
|
|
\fBmvwadd_wch\fP, and
|
|
\fBecho_wchar\fP
|
|
may be macros.
|
|
.SH PORTABILITY
|
|
.PP
|
|
All these functions are described in the XSI Curses standard, Issue 4.
|
|
The defaults specified for forms-drawing characters apply in the POSIX locale.
|
|
.PP
|
|
XSI documents constants beginning with \fBWACS_\fP which are used for
|
|
line-drawing.
|
|
Those are not currently implemented in \fBncurses\fP.
