That's what I thought too, but it doesn't. I need all three modifications
in my aforementioned program, so maybe printf and cout go straight to an
x86 syscall instruction. (I ran objdump on my binary and I could see some
inline x86 syscall instructions).

I had considered intercepting sysall's, but it's not as simple as I first
imagined.
