	       void ); int werase(
	       WINDOW *win ); int clrtobot(
	       void ); int wclrtobot(
	       WINDOW *win ); int clrtoeol(

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       clear, wclear, erase, werase, clrtobot, wclrtobot, clrtoeol, wclrtoeol:	XCURSES4.2

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

DESCRIPTION

       The erase and werase routines copy blanks to every position in the window.

       The clear and wclear routines are similar to erase and werase but also call clearok. The result is 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. In addition, these routines erase the current  line	to
       the right of the cursor, including the character on which the cursor is positioned.

       The clrtoeol and wclrtoeol routines erase the current line to the right of the cursor, including the character on which the cursor is posi-
       tioned.

NOTES

       The header file <curses.h> automatically includes the header file <stdio.h>.

       Note that erase, werase, clear, wclear, clrtobot, and clrtoeol may be macros.

RETURN VALUES

       Upon successful completion, these routines return OK; otherwise, they return ERR.
