NAME
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
SYNOPSIS
#include <curses.h>
int get_wstr(wint_t *wstr);
int getn_wstr(wint_t *wstr, int n);
int wget_wstr(WINDOW *win, wint_t *wstr);
int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);
int mvget_wstr(int y, int x, wint_t *wstr);
int mvgetn_wstr(int y, int x, wint_t *wstr, int n);
int mvwget_wstr(WINDOW *win, int y, int x, wint_t *wstr);
int mvwgetn_wstr(WINDOW *win, int y, int x, wint_t *wstr, int n);
DESCRIPTION
The effect of get_wstr is as though a series of calls to get_wch were made, until a new-
line, other end-of-line, or end-of-file condition is processed. An end-of-file condition
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 ter-
minated by a null wchar_t. The routine places resulting values in the area pointed to by
wstr.
The user's erase and kill characters are interpreted. If keypad mode is on for the win-
dow, KEY_LEFT and KEY_BACKSPACE are both considered equivalent to the user's kill charac-
ter.
Characters input are echoed only if echo is currently on. In that case, backspace is
echoed as deletion of the previous 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.
NOTES
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 recommended.
These functions cannot return KEY_ values because there is no way to distinguish a KEY_
value from a valid wchar_t value.
All of these routines except wgetn_wstr may be macros.
RETURN VALUES
All of these functions return OK upon successful completion. Otherwise, they return ERR.
Functions using a window parameter return an error if it is null.
wgetn_wstr
returns an error if the associated call to wget_wch failed.
PORTABILITY
These functions are described in The Single Unix Specification, Version 2. No error con-
ditions 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 array 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 ven-
dors implement this using wint_t.
