get_wstr, getn_wstr, wget_wstr, wgetn_wstr, mvget_wstr,
mvgetn_wstr, mvwget_wstr, mvwgetn_wstr - get an array of
wide characters from a curses terminal keyboard

The effect of get_wstr is as though a series of calls to
get_wch were made, until a newline, other end-of-line, or
end-of-file condition is processed. An end-of-file condi-
tion is represented by WEOF, as defined in <wchar.h>. The
newline and end-of-line conditions are represented by the
\n wchar_t value. In all instances, the end of the string
is terminated by a null wchar_t. The routine places re-
sulting values in the area pointed to by wstr.
The user's erase and kill characters are interpreted. If
keypad mode is on for the window, KEY_LEFT and
KEY_BACKSPACE are both considered equivalent to the user's
Characters input are echoed only if echo is currently on.
In that case, backspace is echoed as deletion of the pre-
vious character (typically a left motion).
The effect of wget_wstr is as though a series of calls to
wget_wch were made.
The effect of mvget_wstr is as though a call to move and
then a series of calls to get_wch were made.
The effect of mvwget_wstr is as though a call to wmove and
then a series of calls to wget_wch were made.
The getn_wstr, mvgetn_wstr, mvwgetn_wstr, and wgetn_wstr
functions are identical to the get_wstr, mvget_wstr,
mvwget_wstr, and wget_wstr functions, respectively, except
that the *n_* versions read at most n characters, letting
the application prevent overflow of the input buffer.
Using get_wstr, mvget_wstr, mvwget_wstr, or wget_wstr to
read a line that overflows the array pointed to by wstr
causes undefined results. The use of getn_wstr,
mvgetn_wstr, mvwgetn_wstr, or wgetn_wstr, respectively, is
These functions cannot return KEY_ values because there is
no way to distinguish a KEY_ value from a valid wchar_t
All of these routines except wgetn_wstr may be macros.
All of these functions return OK upon successful comple-
tion. Otherwise, they return ERR.
Functions using a window parameter return an error if it
returns an error if the associated call to
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 wget_wch 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 WEOF followed by a null wchar_t.
X/Open curses documents these functions to pass an array
of wchar_t, but all of the vendors implement this using
Functions: curses(3x), curs_get_wch(3x), curs_getstr(3x).
