int erase(void); int werase(WINDOW win); int clear(void); int wclear(WINDOW win); int clrtobot(void); int wclrtobot(WINDOW win); int clrtoeol(void); int wclrtoeol(WINDOW win);
The clear and wclear routines are like erase and werase, but they also call clearok, so that the screen is cleared completely on the next call to wrefresh for that window and repainted from scratch.
The clrtobot and wclrtobot routines erase all lines below the cursor in the window. Also, the current line to the right of the cursor, inclusive, is erased.
The clrtoeol and wclrtoeol routines erase the current line to the right of the cursor, inclusive.
Note that erase, werase, clear, wclear, clrtobot, and clrtoeol may be macros.
