Can I use tparm() without tputs or putp

My understanding is that the function char *tparm(char *str, ...); just converts the given string str to an expanded parameterized version which will be fine to use with stdout outputting functions like printf or cout. But the man page mentions -

Parameterized strings should be passed through tparm to instantiate them. All terminfo strings [including the output of tparm] should be printed with tputs or putp.

So can I parse terminfo entries and use tparm() on them passing appropriate parameters and output them using stdout output functions? Also I'm doing the checks of non-tty output and ignoring these methods so I got that base covered.

Sure, you can. But some capability strings include padding and time delays, which tparm assumes will be interpreted by tputs.

For instance, the flash capability would use time-delays, which are passed along to tputs (using the syntax described in the terminfo(5) manual page).
