[FFmpeg-devel] Off topic question about format specifiers in the C stdlib

[Marcus Johnson]

No, I'm writing my own codec from the ground up; not an implementation of
one that already exists based on a standardized codec like jpeg, but my own
from scratch.

I noticed that printf and scanf support format specifiers, so I was
wondering if there was a function like getopt, but specifically for input
and output, but I guess not.
