+DESCRIPTION
The addch, waddch, mvaddch and mvwaddch routines put the character ch into the given window at its current window position, which is then advanced. They are analogous to putchar in stdio(3). If the advance is at the right mar- - gin, the cursor automatically wraps to the beginning of - the next line. At the bottom of the current scrolling - region, if scrollok is enabled, the scrolling region is - scrolled up one line. - - If ch is a tab, newline, or backspace, the cursor is moved - appropriately within the window. Backspace moves the cur- - sor one character left; at the left edge of a window it - does nothing. Newline does a clrtoeol, then moves the - cursor to the window left margin on the next line, - scrolling the window if on the last line. Tabs are con- - sidered to be at every eighth column. The tab interval - may be altered by setting the TABSIZE variable. - - If ch is any control character other than tab, newline, or - backspace, it is drawn in ^X notation. Calling winch - after adding a control character does not return the char- - acter itself, but instead returns the ^-representation of - the control character. + gin: + + o The cursor automatically wraps to the beginning of the + next line. + + o At the bottom of the current scrolling region, and if + scrollok is enabled, the scrolling region is scrolled + up one line. + + o If scrollok is not enabled, writing a character at the + lower right margin succeeds.
