| 11 Synopsis: | |
| 12 chtype inch(void); | |
| 13 chtype winch(WINDOW *win); | |
| 14 chtype mvinch(int y, int x); | |
| 15 chtype mvwinch(WINDOW *win, int y, int x); | |
| 16 | |
| 17 int in_wch(cchar_t *wcval); | |
| 18 int win_wch(WINDOW *win, cchar_t *wcval); | |
| 19 int mvin_wch(int y, int x, cchar_t *wcval); | |
| 20 int mvwin_wch(WINDOW *win, int y, int x, cchar_t *wcval); | |
| 21 | |
| 22 Description: | |
| 23 The inch() functions retrieve the character and attribute from | |
| 24 the current or specified window position, in the form of a | |
| 25 chtype. If a NULL window is specified, (chtype)ERR is returned. | |
| 26 | |
| 27 The in_wch() functions are the wide-character versions; instead | |
| 28 of returning a chtype, they store a cchar_t at the address | |
| 29 specified by wcval, and return OK or ERR. (No value is stored | |
| 30 when ERR is returned.) Note that in PDCurses, chtype and cchar_t | |
| 31 are the same. | |
