in_wchstr, in_wchnstr, win_wchstr, win_wchnstr, mvin_wchstr,
mvin_wchnstr, mvwin_wchstr, mvwin_wchnstr - get an array of complex
characters and renditions from a curses window
#include <curses.h>
int in_wchstr(cchar_t *wchstr);
int in_wchnstr(cchar_t *wchstr, int n);
int win_wchstr(WINDOW *win, cchar_t *wchstr);
int win_wchnstr(WINDOW *win, cchar_t *wchstr, int n);
int mvin_wchstr(int y, int x, cchar_t *wchstr);
int mvin_wchnstr(int y, int x, cchar_t *wchstr, int n);
int mvwin_wchstr(WINDOW *win, int y, int x, cchar_t *wchstr);
int mvwin_wchnstr(WINDOW *win, int y, int x, cchar_t *wchstr, int n);
These functions return an array of complex characters in wchstr,
starting at the current cursor position in the named window.
Attributes (rendition) are stored with the characters.
The in_wchnstr, mvin_wchnstr, mvwin_wchnstr and win_wchnstr fill the
array with at most n cchar_t elements.
Note that all routines except win_wchnstr may be macros.
Reading a line that overflows the array pointed to by wchstr with
in_wchstr, mvin_wchstr, mvwin_wchstr or win_wchstr causes undefined
results. Therefore, the use of in_wchnstr, mvin_wchnstr,
mvwin_wchnstr, or win_wchnstr is recommended.
Upon successful completion, these functions return OK. Otherwise,
they return ERR.
Functions with a "mv" prefix first perform a cursor movement using
wmove, and return an error if the position is outside the window, or
if the window pointer is null.
The XSI Curses defines no error conditions. This implementation
checks for null pointers, returning ERR in that case.
Functions: curses(3X), curs_in_wch(3X), curs_instr(3X),
curs_inwstr(3X) curs_inchstr(3X)
