Description

The in_wchstr() and win_wchstr() functions retrieve a complex character string (with rendition) starting at the current cursor position of the stdscr window and window win, respectively, and ending at the right margin. The mvin_wchstr() and mvwin_wchstr() functions retrieve a complex 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 in_wchnstr(), win_wchnstr(), mvin_wchnstr(), and mvwin_wchnstr() 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 retrieve the string, starting at the position specified by the x and y parameters.

The retrieved character string (with renditions) is stored in the object pointed to by wcval.

Parameters

wchstr: Is a pointer to an object where the retrieved complex character string can be stored.
n: Is the number of characters not to exceed when retrieving wchstr.
y: Is the y (row) coordinate of the starting position of the string to be retrieved.
x: 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.

Return Values

On success, these functions return OK. Otherwise, they return ERR.

Errors

None.
