tevent_wait_send() and tevent_wait_recv() are not documented but used quiet frequently for tevent async calls in the samba code.
There is exactly one place where those functions are used: For doing deferred closes in the s3 file server. The implementation contains the comment
* Just wait for getting a tevent_wait_done. tevent_wait_done can deal with a
* NULL request.
Correct, the file does not contain proper doxygen comments, but such a rarely used smbd-internal helper function does not require full doxygen documentation from my point of view. We don't yet have the formal requirement to document each and every function properly in our README.Coding, so I'm closing this one as WONTFIX.
