### Synopsis
|
|
|
|
chtype inch(void);
|
|
chtype winch(WINDOW *win);
|
|
chtype mvinch(int y, int x);
|
|
chtype mvwinch(WINDOW *win, int y, int x);
|
|
|
|
int in_wch(cchar_t *wcval);
|
|
int win_wch(WINDOW *win, cchar_t *wcval);
|
|
int mvin_wch(int y, int x, cchar_t *wcval);
|
|
int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval);
|
|
|
|
### Description
|
|
|
|
The inch() functions retrieve the character and attribute from the
|
|
current or specified window position, in the form of a chtype. If a
|
|
NULL window is specified, (chtype)ERR is returned.
|
|
|
|
The in_wch() functions are the wide-character versions; instead of
|
|
returning a chtype, they store a cchar_t at the address specified by
|
|
wcval, and return OK or ERR. (No value is stored when ERR is
|
|
returned.) Note that in PDCurses, chtype and cchar_t are the same.
|
|
|
