Thread: format modifier percent z (%z) ?

So as always the documentation surprises me [as a beginner] and I see this %z used inside printf while it's not listed in the list of format modifiers of printf! So what is it really?

Code:

printf("size = %zu\n", size);

Or you could read the manual which says

ssize_t argument, or a following n conversion corresponds to a

Thanks, Ah, I did "man printf" and it wasn't listed there too, now I did "man 3 printf" and it's there! Thanks.

That's the annoying thing about printf, is that the command-line command gets found first. I usually cheat and do "man fprintf" because (a) it's one less character and (b) for some reason my brain remembers that better than the "3".

Hmmm, that's funny and useful Thanks.
