#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 ); LIBRARY
Curses Library (libcurses) STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: get_wstr, getn_wstr, wget_wstr, wgetn_wstr, mvget_wstr, mvgetn_wstr, mvwget_wstr, mvwgetn_wstr: XCURSES4.2 Refer to the standards(5) reference page for more information about industry standards and associated tags. DESCRIPTION
The effect of get_wstr is as though a series of calls to get_wch were made, until a newline, end-of-line, or end-of-file character is pro- cessed. An end-of-file character is represented by WEOF, as defined in <wchar.h>. A newline or end-of-line character is represented as its wchar_t value. In all instances, the end of the string is terminated by a null wchar_t. The routine places resulting values in the area pointed to by wstr. The routine's interpretation of the user's erase and kill characters affects the sequence of characters returned. 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 as there is no way to distinguish a KEY_ value from a valid wchar_t value. The header file <curses.h> automatically includes the header file <stdio.h>. Note that all routines except wgetn_wstr may be macros. RETURN VALUES
All these functions return OK upon successful completion. Otherwise, they return ERR. SEE ALSO

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 newline, 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 repre- sented by the wchar_t value. In all instances, the end of the string is terminated 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 window, KEY_LEFT and KEY_BACKSPACE are both considered equivalent to the user's kill character. Characters input are echoed only if echo is currently on. In that case, backspace is echoed as deletion of the previous character (typi- cally 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. PORTABILITY
These functions are described in The Single Unix Specification, 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 array contains a WEOF followed by a null wchar_t. SEE ALSO
