I have a action which execute the deferred transaction . Let I send the delay of 20 days . If I want to cancel the deferred transaction before 20 days . Is there any way I can do this ?

This is my action which I push to deferred the transaction .

void second::send(account_name from , account_name to ,asset  quantity,string  memo,uint64_t delay) {
            eosio::transaction t{};

        eosio::permission_level(from, N(active)),       
            t.delay_sec = delay;
            t.send(N(memo), from);

transfer( account_name from,
                      account_name to,
                      asset        quantity,
                      string      memo  ){....}

transfer is my action that execute the transaction .

  • How can we use the function defined in apply_context.hpp file to cancel a deffered transaction bool apply_context::cancel_deferred_transaction( const uint128_t& sender_id, account_name sender ) {....} – Nirdesh Kumar Choudhary Aug 3 '18 at 9:05
  • The absolute path of function 'cancel_deferred_transaction ()' is /eos/libraries/chain/include/eosio/chain/apply_context.hpp – Nirdesh Kumar Choudhary Aug 3 '18 at 9:14
  • You can import eosio library in your file to use it. – Rajat Chaudhary Aug 3 '18 at 10:47
  • Yes I found the library but what is context here , the parameter that I have to pass. – Nirdesh Kumar Choudhary Aug 3 '18 at 12:30
void send(const uint128_t& sender_id, account_name payer, bool replace_existing = false)

First parameter(sender_id) is the id of the deferred transaction. You can call cancel_deferred(sender_id) to cancel it.

See example in delegate_bandwidth on GitHub.
