.SH NAME
\fBget_wstr\fR,
\fBgetn_wstr\fR,
\fBmvgetn_wstr\fR,
\fBmvwget_wstr\fR,
\fBmvwgetn_wstr\fR \- get an array of wide characters from a curses terminal keyboard
+.ad
+.hy
.SH SYNOPSIS
.nf
\fB#include <curses.h>\fR
-
+.sp
\fBint get_wstr(wint_t *\fR\fIwstr\fR\fB);\fR
.br
\fBint getn_wstr(wint_t *\fR\fIwstr\fR\fB, int \fR\fIn\fR\fB);\fR
The newline and end-of-line conditions are represented by the \fB\\n\fR \fBwchar_t\fR value.
In all instances, the end of the string is terminated by a null \fBwchar_t\fR.
The routine places resulting values in the area pointed to by \fIwstr\fR.
-
+.PP
The user's erase and kill characters are interpreted. If keypad
mode is on for the window, \fBKEY_LEFT\fR and \fBKEY_BACKSPACE\fR
are both considered equivalent to the user's kill character.
-
+.PP
Characters input are echoed only if \fBecho\fR is currently on. In that case,
backspace is echoed as deletion of the previous character (typically a left
motion).
-
+.PP
The effect of
\fBwget_wstr\fR
is as though a series of
calls to
\fBwget_wch\fR
were made.
-
+.PP
The effect of
\fBmvget_wstr\fR
is as though a call to
\fBget_wch\fR
were
made.
-
+.PP
The effect of
\fBmvwget_wstr\fR
is as though a call to
and then a series of calls to
\fBwget_wch\fR
were made.
-
+.PP
The
\fBgetn_wstr\fR,
\fBmvgetn_wstr\fR,
\fBmvgetn_wstr\fR,
\fBmvwgetn_wstr\fR, or
\fBwgetn_wstr\fR, respectively, is recommended.
-
+.PP
These functions cannot return \fBKEY_\fR values because there
is no way to distinguish a \fBKEY_\fR value from a valid \fBwchar_t\fR value.
-
+.PP
All of these routines except \fBwgetn_wstr\fR may be macros.
.SH RETURN VALUES
All of these functions return \fBOK\fR upon successful completion.
Otherwise, they return \fBERR\fR.
+.PP
+Functions using a window parameter return an error if it is null.
+.RS
+.TP 5
+\fBwgetn_wstr\fP
+returns an error if the associated call to \fBwget_wch\fP failed.
+.RE
.SH PORTABILITY
These functions are described in The Single Unix Specification, Version 2.
No error conditions are defined.
In the latter case,
an ERR return without other data is treated as an end-of-file condition,
and the returned array contains a \fBWEOF\fR followed by a null \fBwchar_t\fR.
+.PP
+X/Open curses documents these functions to pass an array of \fBwchar_t\fR,
+but all of the vendors implement this using \fBwint_t\fR.
