So, using a buffer as both a source and a destination in sprintf() doesn't seem to be explicitly non-compliant. Like this: /* write something into buf */ sprintf(buf, "hello"); /* now use buf as a source string, and a destination. */ sprintf(buf, "(%s)", buf); And yet, i don't think it would be reasonable of me, given the rest of C, to expect this to work. #C

Hi everyone! This is my first post here in the Fediverse. Most of what I am and I do is already covered in my Bio, so I'll keep this short: I'm a FOSS developer and very often I'm into low level, reverse engineering and retrocomputing stuff. Since 2017, I've been working on my own disassembler engine written in C to challenge myself and learn what it's like to build reverse engineering tools instead of just using them. I'm looking forward to learning more and sharing knowledge with you all! #Introduction #ReverseEngineering #OpenSource #FOSS #C
