|
|
chtype inch(void);
|
|
chtype winch(WINDOW *win);
|
|
chtype mvinch(int y, int x);

chtype mvwinch(WINDOW *win, int y, int x);

|

|
|
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.
