In certain code that I have to take care of, I have seen a structure specifier %*s . Can anyone convey to me what This is certainly and why it truly is employed?

Employing %s in scanf with out an explcit subject width opens exactly the same buffer overflow exploit that will get did; specifically, if you will find additional people within the input stream when compared to the target buffer is sized to hold, scanf will happily compose All those extra characters to memory exterior the buffer, potentially clobbering one thing critical. Regretably, unlike in printf, you can't supply the sphere with to be a operate time argument:
