int innwstr(wchar_t *wstr, int n);

int inwstr(wchar_t *wstr);

int mvinnwstr(int y, int x, wchar_t *wstr, int n);

int mvinwstr(int y, int x, wchar_t *wstr);

int mvwinnwstr(WINDOW*win, int y, int x, wchar_t *wstr, int n);

int mvwinwstr(WINDOW*win, int y, int x, wchar_t *wstr);

int winwstr(WINDOW*win, wchar_t *wstr);

int winnwstr(WINDOW*win, wchar_t *wstr, int n);

PARAMETERS

wstr

: Is a pointer to an object that can hold the retrieved multibyte character string.

: Is the number of characters not to exceed when retrieving wstr.

: Is the y (row) coordinate of the starting position of the string to be retrieved.

: Is the x (column) coordinate of the starting position of the string to be retrieved.

win

: Is a pointer to the window in which the string is to be retrieved.

DESCRIPTION

The inwstr() and winwstr() functions retrieve a wide character string (without attributes) starting at the current cursor position of the stdscr window and window win, respectively, and ending at the right margin. The mvinwstr() and mvwinwstr() functions retrieve a wide character string located at the position indicated by the x (column) and y (row) parameters (the former in the stdscr window; the latter in window win).

The innwstr(), winnwstr(), mvinnwstr(), and mvwinnwstr() functions retrieve at most n characters from the window stdscr and win, respectively. The former two functions retrieve the string starting at the current cursor position; the latter two commands return the string, starting at the position specified by the x and y parameters.

All these functions store the retrieved string in the object pointed to by wstr. They only store complete wide characters. If the area pointed to by wstr is not large enough to hold at least one character, these functions fail.

Only the character portion of the character/rendition pair is returned. To return the complete character/rendition pair, use win_wchstr(3XCURSES).

RETURN VALUES

On success, the inwstr(), mvinwstr(), mvwinwstr(), and winwstr() functions return OK. Otherwise, they return ERR.

On success, the innwstr(), mvinnwstr(), mvwinnwstr(), and winnwstr() functions return the number of characters read into the string. Otherwise, they return ERR.
