- These routines insert a character string (as many charac- - ters as will fit on the line) before the character under - the cursor. All characters to the right of the cursor are - shifted right, with the possibility of the rightmost char- - acters on the line being lost. The cursor position does - not change (after moving to y, x, if specified). The four - routines with n as the last argument insert a leading sub- - string of at most n characters. If n<=0, then the entire - string is inserted. - - If a character in str is a tab, newline, carriage return - or backspace, the cursor is moved appropriately within the - window. A newline also does a clrtoeol before moving. - Tabs are considered to be at every eighth column. If a - character in str is another control character, it is drawn - in the ^X notation. Calling winch after adding a control - character (and moving to it, if necessary) does not return - the control character, but instead returns a character in - the ^-representation of the control character. +
