Source Code

function transfer(address _to, uint256 _value) public returns (bool) {
  require(_to != address(0));
  require(_value <= balances[msg.sender]);

  // SafeMath.sub will throw if there is not enough balance.
  balances[msg.sender] = balances[msg.sender].sub(_value);
  balances[_to] = balances[_to].add(_value);
  Transfer(msg.sender, _to, _value);
  return true;
}

allowance

Parameters

Name	Type
_owner	address
_spender	address

Properties

Visibility public

Mutability view

Source Code

function allowance(address _owner, address _spender)
  public
  view
  returns (uint256)
{
  return allowed[_owner][_spender];
}

transferFrom

Parameters

Name	Type
_from	address
_to	address
_value	uint256

Properties

Visibility public

Mutability transaction

Requirements

_to must not be equal to UNKNOWN VALUE

_value must be less than or equal to balances for _from

_value must be less than or equal to allowed for _from for the sender's address

Source Code

function transferFrom(
