This is the right info.  Be sure to scroll up to see how to use tgetent, 
tgetstr, and tputs.  You aren't likely to need any padding.

Essentially:
     tgetent using getenv("TERM")    gets you the whole entry from 
/etc/termcap
     tgetstr of "cl"                            gets you the "clear" 
sequence
     tputs                                        outputs the "clear" 
sequence
