//! @brief Example Rust-based BPF program that moves a lamport from one account to another
extern crate solana_sdk;
use solana_sdk::entrypoint;
use solana_sdk::entrypoint::*;
use solana_sdk::pubkey::Pubkey;
use solana_sdk::{account_info::AccountInfo, entrypoint, entrypoint::SUCCESS, pubkey::Pubkey};

fn process_instruction(_program_id: &Pubkey, accounts: &mut [AccountInfo], _data: &[u8]) -> u32 {
// account 0 is the mint and not owned by this program, any debit of its lamports
// should result in a failed program execution. Test to ensure that this debit
// is seen by the runtime and fails as expected
*ka[0].lamports -= 1;
*accounts[0].lamports -= 1;
SUCCESS
