+ amend changes for tput to reset tty modes to "sane" if the program is run as "reset", like tset. Likewise, ensure that tset sends either reset- or init-strings. + improve manual page descriptions of tput init/reset and tset/reset, to make it easier to see how they are similar and different. + move a static result from key_name() to _nc_globals + modify _nc_get_screensize to allow for use_env() and use_tioctl() state to be per-screen when sp-funcs are configured, better matching the behavior when using the term-driver configuration. + improve cross-references in manual pages for often used functions + move SCREEN field for use_tioctl() data before the ncursesw fields, and limit that to the sp-funcs configuration to improve termlib compatibility (cf: 20120714). + correct order of initialization for traces in use_env() and use_tioctl() versus first trace calls.

|
|
The effect of <STRONG>get_wstr</STRONG> is as though a series of calls to
|
|
<STRONG><A HREF="curs_get_wch.3x.html">get_wch(3x)</A></STRONG> were made, until a newline, other end-of-line,
|
|
or end-of-file condition is processed. An end-of-file
|
|
condition is represented by <STRONG>WEOF</STRONG>, as defined in <STRONG><wchar.h></STRONG>.
|
|
The newline and end-of-line conditions are represented by
|
|
the <STRONG>\n</STRONG> <STRONG>wchar_t</STRONG> value. In all instances, the end of the
|
|
string is terminated by a null <STRONG>wchar_t</STRONG>. The routine
|
|
places resulting values in the area pointed to by <EM>wstr</EM>.
|
|
|
|
The user's erase and kill characters are interpreted. If
|
|
keypad mode is on for the window, <STRONG>KEY_LEFT</STRONG> and
|
|
<STRONG>KEY_BACKSPACE</STRONG> are both considered equivalent to the user's
|
|
kill character.
|
|
|
|
Characters input are echoed only if <STRONG>echo</STRONG> is currently on.
|
|
In that case, backspace is echoed as deletion of the pre-
|
|
vious character (typically a left motion).
|
|
|
|
The effect of <STRONG>wget_wstr</STRONG> is as though a series of calls to
|
|
<STRONG>wget_wch</STRONG> were made.
|
|
|
|
The effect of <STRONG>mvget_wstr</STRONG> is as though a call to <STRONG>move</STRONG> and
|
|
then a series of calls to <STRONG>get_wch</STRONG> were made.
|
|
|
|
The effect of <STRONG>mvwget_wstr</STRONG> is as though a call to <STRONG>wmove</STRONG> and
|
|
then a series of calls to <STRONG>wget_wch</STRONG> were made.
|
|
|
|
The <STRONG>getn_wstr</STRONG>, <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, and <STRONG>wgetn_wstr</STRONG>
|
|
functions are identical to the <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>,
|
|
<STRONG>mvwget_wstr</STRONG>, and <STRONG>wget_wstr</STRONG> functions, respectively, except
|
|
that the <STRONG>*n_*</STRONG> versions read at most <EM>n</EM> characters, letting
|
|
the application prevent overflow of the input buffer.
|
|
|
|
|
|
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
|
|
Using <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>, <STRONG>mvwget_wstr</STRONG>, or <STRONG>wget_wstr</STRONG> to
|
|
read a line that overflows the array pointed to by <STRONG>wstr</STRONG>
|
|
causes undefined results. The use of <STRONG>getn_wstr</STRONG>,
|
|
<STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, or <STRONG>wgetn_wstr</STRONG>, respectively, is
|
|
recommended.
|
|
|
|
These functions cannot return <STRONG>KEY_</STRONG> values because there is
|
|
no way to distinguish a <STRONG>KEY_</STRONG> value from a valid <STRONG>wchar_t</STRONG>
|
|
value.
|
|
|
|
All of these routines except <STRONG>wgetn_wstr</STRONG> may be macros.
|
|
|
|
|
|
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
|
|
All of these functions return <STRONG>OK</STRONG> upon successful comple-
|
|
tion. Otherwise, they return <STRONG>ERR</STRONG>.
|
|
|
|
Functions using a window parameter return an error if it
|
|
is null.
|
|
|
|
<STRONG>wgetn_wstr</STRONG>
|
|
returns an error if the associated call to
|
|
<STRONG>wget_wch</STRONG> failed.
|
|
|
|
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.
|
|
|
|
|
|
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
|
|
These functions are described in The Single Unix Specifi-
|
|
cation, Version 2. No error conditions are defined. This
|
|
implementation returns ERR if the window pointer is null,
|
|
or if the lower-level <STRONG>wget_wch</STRONG> call returns an ERR. In
|
|
the latter case, an ERR return without other data is
|
|
treated as an end-of-file condition, and the returned ar-
|
|
ray contains a <STRONG>WEOF</STRONG> followed by a null <STRONG>wchar_t</STRONG>.
|
|
|
|
X/Open curses documents these functions to pass an array
|
|
of <STRONG>wchar_t</STRONG>, but all of the vendors implement this using
|
|
<STRONG>wint_t</STRONG>.
