Kind of unrelated, why does c sometimes fail to print if it hits a breakpoint right after a print while debugging? Or if it segfaults right after too iirc
Without knowing the details of C, I've seen this in other languages and it's usually something with missing a flush or a buffered output mode or something like that.
does anything flush the buffers after the print, but before the break? otherwise, if the stream you're printing to is buffered, you're not necessarily gonna see any output
I don't know, I just use printf
Im pretty sure its because of char 13 (carriage return). This char sets cursor to the start of the line overwriting whatever was printed there (in most terminals). I belive that some error messages use this char and when you print something the char at the begining or end of the error message overwrites your message. A workaround is simply printing a newline after or before your message.
