to be output by 
.PN addstr .
.PP
The routine
.PN wprintw
adds a string to the specified window starting at the current 
cursor position.
This routine causes the string
that would normally be output by 
.PN printf 
to be output by 
.PN waddstr .
.PP
The routine
.PN mvprintw
adds a string to the default window starting at the specified 
cursor position.
This routine causes the string
that would normally be output by 
.PN printf 
to be output by 
.PN addstr .
.PP
The routine
.PN mvwprintw
adds a string to the specified window starting at the specified 
cursor position.
This routine causes the string
that would normally be output by 
.PN printf 
to be output by 
.PN waddstr .
.PP
All these routines are analogous to 
.PN printf .
It is advisable to use the field width options of 
.PN printf  
to avoid leaving unwanted characters on the screen from earlier calls.
