Examples
use solana_program::{
account_info::{AccountInfo, next_account_info, next_account_infos},
entrypoint::ProgramResult,
pubkey::Pubkey,
};
pub fn process_instruction(
program_id: &Pubkey,
accounts: &[AccountInfo],
instruction_data: &[u8],
) -> ProgramResult {
let accounts_iter = &mut accounts.iter();
let signer = next_account_info(accounts_iter)?;
let payer = next_account_info(accounts_iter)?;
let outputs = next_account_infos(accounts_iter, 3)?;
// do stuff ...
Ok(())
