| Name: inch |
| |
| 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. |
