Currently there are /znc clearallchannelbuffers and /znc clearallquerybuffers. /znc clearallbuffers to clear both channel and query buffers could be useful especially with mobile client.

I actually have this as my own addon aliased to /clr for exactly this reason!

I thought it was a bit niche so I haven't PRd it, but:

#include <znc/Chan.h>
#include <znc/IRCNetwork.h>
#include <znc/Modules.h>
#include <znc/Query.h>
#include <znc/User.h>

class CClearAllBuffers : public CModule {
public:
        MODCONSTRUCTOR(CClearAllBuffers) {}

        virtual void OnModCommand(const CString& sCommand) {
            int count = 0;

            for (auto network : m_pUser->GetNetworks()) {
                for (auto chan : network->GetChans()) {
                    chan->ClearBuffer();
                    count++;
                }
                for (auto query : network->GetQueries()) {
                    network->DelQuery(query->GetName());
                    count++;
                }
            }

            PutStatus("Cleared " + CString(count) + " buffers");
        }
};

USERMODULEDEFS(CClearAllBuffers, "Provides command to clear ALL buffers")

Oh and if you just want the current network, simply use *alias:

<*alias> Actions for alias CL:
<*alias> 0   ZNC ClearAllChannelBuffers
<*alias> 1   ZNC ClearAllQueryBuffers
<*alias> End of actions for alias CL.
