It's not as complex as you make out.
Both termcap(3) and terminfo(3) calls return data from the terminfo 
database. As every program pass this to tgoto(3) for termcap, or 
tputs(3) for terminfo the diagram goes like this

terminfo programs:
terminfo database ----> program

termcap programs:
terminfo database ----> program

Why don't you go and readup on what I've implemented, as you're making 
assumptions about how it must work and how complex it must be which is 
definitely not the case.
