@brief Externally maintained code
|
|
|
|
The "ext" directory holds code that was written elsewhere, and is not
|
|
reliably packaged as a library where we want to build, so we ship
|
|
it along with Tor.
|
|
|
|
In general, you should not edit this code: we are not the maintainers.
|
|
Instead, you should submit patches upstream.

tor_queue.h
|
|
|
|
> A copy of sys/queue.h from OpenBSD. We keep our own copy rather
|
|
> than using sys/queue.h, since some platforms don't have a

|
> sys/queue.h, and the ones that do have diverged in incompatible
|
|
> ways. (CIRCLEQ or no CIRCLEQ? SIMPLQ or STAILQ?) We also rename
|
|
> the identifiers with a TOR_ prefix to avoid conflicts with
|
|
> the system headers.
