sprintf has no effect in multiple compilation units
PostPosted: Mon Jan 18, 2016 5:16 pm     Reply with quote
Hello,

I have noticed a strange behavior of sprintf function. It has no effect when called within a C file other than the main one in multiple compilation units. If I move the same statement to the main() function, it works normally.

Any thoughts?
Thanks

What is it printing to? Is that something "visible" in both compilation units/files?

Hello newguy,

No, it's not visible to both units; just to the one I'm calling from. Should it be visible to both?

Thanks
