I think the title describes everything, but the story is
I’m re-implementing the bzero function in c, and
that’s where I encountered this aq\0aq
by some searching I understood that it has the same role as \0(which is a null character to determine the end of a string)
but I’m curious if there’s any difference and what is the aq?
>Solution :
what is the aq?
It’s an artifact left by converting groff (man pages, see man 7 groff) to html. It should be just '\0'. See man bzero.
https://github.com/mkerrisk/man-pages/blob/master/man3/bzero.3#L45
by writing zeros (bytes containing \(aq\e0\(aq) to that area.
