Starter

Starter is the simplest possible hook: it just accepts all transactions and logs that it is running.

to test:

• in the develop pane, compile starter.c
• in the deploy pane, deploy it to Alice account
• set up payment transaction from Alice to Bob
• run it and see in the debug stream 'Accept.c: Called.'

Modifying the tracing message and compiling with different optimizations are left as an exercise for the reader.

starter.c

/**
 * This hook just accepts any transaction coming through it
 */
#include "hookapi.h"

int64_t hook(uint32_t reserved ) {

    TRACESTR("Accept.c: Called.");
    accept (0,0,0); 

    _g(1,1);   // every hook needs to import guard function and use it at least once
    // unreachable
    return 0;
}
