+.SH DESCRIPTION
+.SS erase/werase
+The \fBerase\fP and \fBwerase\fP routines copy blanks to every
+position in the window, clearing the screen.
+.PP
+Blanks created by erasure have the current background rendition (as set
+by \fBwbkgdset\fP(3X)) merged into them.
+.SS clear/wclear
+.PP
+The \fBclear\fP and \fBwclear\fP routines are like \fBerase\fP and
+\fBwerase\fP, but they also call \fBclearok\fP(3X), so that the screen is
+cleared completely on the next call to \fBwrefresh\fP for that window
+and repainted from scratch.
+.SS clrtobot/wclrtobot
+.PP
+The \fBclrtobot\fP and \fBwclrtobot\fP routines erase from the cursor to the
+end of screen.
+That is, they erase all lines below the cursor in the window.
+Also, the current line to the right of the cursor, inclusive, is erased.
+.SS clrtoeol/wclrtoeol
+.PP
+The \fBclrtoeol\fP and \fBwclrtoeol\fP routines erase the current line
+to the right of the cursor, inclusive, to the end of the current line.
+.SH RETURN VALUE
+All routines return the integer \fBOK\fP on success and \fBERR\fP on failure.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+.bP
+functions using a window pointer parameter return an error if it is null
+.bP
+\fBwclrtoeol\fP returns an error
+if the cursor position is about to wrap.
+.SH NOTES
+Note that \fBerase\fP, \fBwerase\fP, \fBclear\fP, \fBwclear\fP,
+\fBclrtobot\fP, and \fBclrtoeol\fP may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+The
+standard specifies that they return \fBERR\fP on failure, but specifies no
+error conditions.
+.PP
+The SVr4.0 manual says that these functions could
+return "a non-negative integer if \fBimmedok\fP(3X) is set",
+referring to the return-value of \fBwrefresh\fP.
+In that implementation, \fBwrefresh\fP would return a count of
+the number of characters written to the terminal.
+.PP
+Some historic curses implementations had, as an undocumented feature, the
+ability to do the equivalent of \fBclearok(..., 1)\fP by saying
+\fBtouchwin(stdscr)\fP or \fBclear(stdscr)\fP.
+This will not work under
+ncurses.
+.PP
+This implementation, and others such as Solaris,
+sets the current position to 0,0 after erasing
+via \fBwerase\fP and \fBwclear\fP.
+That fact is not documented in other implementations,
+and may not be true of implementations
+which were not derived from SVr4 source.
+.PP
+Not obvious from the description,
+most implementations clear the screen after \fBwclear\fP
+even for a subwindow or derived window.
+If you do not want to clear the screen during the next \fBwrefresh\fP,
+use \fBwerase\fP instead.
