ncurses 5.3
2002-10-13 11:35:53 +08:00
The <STRONG>vwscanw</STRONG> and <STRONG>vw_scanw</STRONG> routines are analogous to <STRONG>vscanf</STRONG>.
They perform a <STRONG>wscanw</STRONG> using a variable argument list. The
third argument is a <EM>va</EM><STRONG>_</STRONG><EM>list</EM>, a pointer to a list of argu-
ments, as defined in <STRONG>&lt;stdarg.h&gt;</STRONG>.

<H2>RETURN VALUE</H2><PRE>
ncurses 5.3
2002-10-13 11:35:53 +08:00
<STRONG>vwscanw</STRONG> returns <STRONG>ERR</STRONG> on failure and an integer equal to the
ncurses 5.1
2000-07-09 10:46:08 +08:00
number of fields scanned on success.
ncurses 5.3
2002-10-13 11:35:53 +08:00
Applications may use the return value from the <STRONG>scanw</STRONG>,
<STRONG>wscanw</STRONG>, <STRONG>mvscanw</STRONG> and <STRONG>mvwscanw</STRONG> routines to determine the
ncurses 5.1
2000-07-09 10:46:08 +08:00
number of fields which were mapped in the call.
ncurses 5.7 - patch 20100918 + regenerated html manpages. + minor fixes for symlinks to curs_legacy.3x and curs_slk.3x manpages. + add manpage for sp-funcs. + add sp-funcs to test/listused.sh, for documentation aids.
2010-09-19 08:45:46 +08:00
Functions with a "mv" prefix first perform a cursor move-
ment using <STRONG>wmove</STRONG>, and return an error if the position is
outside the window, or if the window pointer is null.

<H2>PORTABILITY</H2><PRE>
The XSI Curses standard, Issue 4 describes these func-
ncurses 5.3
2002-10-13 11:35:53 +08:00
tions. The function <STRONG>vwscanw</STRONG> is marked TO BE WITHDRAWN,
and is to be replaced by a function <STRONG>vw_scanw</STRONG> using the
<STRONG>&lt;stdarg.h&gt;</STRONG> interface. The Single Unix Specification, Ver-
sion 2 states that <STRONG>vw_scanw</STRONG> is preferred to <STRONG>vwscanw</STRONG> since
the latter requires including <STRONG>&lt;varargs.h&gt;</STRONG>, which cannot be
used in the same file as <STRONG>&lt;stdarg.h&gt;</STRONG>. This implementation
uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because that header is included
in <STRONG>&lt;curses.h</STRONG>&gt;.
Both XSI and The Single Unix Specification, Version 2
state that these functions return ERR or OK. Since the
underlying <STRONG>scanf</STRONG> can return the number of items scanned,
and the SVr4 code was documented to use this feature, this
is probably an editing error which was introduced in XSI,
rather than being done intentionally. Portable applica-
tions should only test if the return value is ERR, since
the OK value (zero) is likely to be misleading. One pos-
sible way to get useful results would be to use a "%n"
conversion at the end of the format string to ensure that
something was processed.
