Function Call

core/vm/runtime/runtime.go:148–164

Call executes the code given by the contract's address. It will return the EVM's return value or an error if it failed. Call, unlike Execute, requires a config and also requires the State field to be set.

(address common.Address, input []byte, cfg *Config)

// Call, unlike Execute, requires a config and also requires the State field to
// be set.
func Call(address common.Address, input []byte, cfg *Config) ([]byte, uint64, error) {
	setDefaults(cfg)

	vmenv := NewEnv(cfg)

	sender := cfg.State.GetOrNewStateObject(cfg.Origin)
	// Call the code with the given configuration.
	ret, leftOverGas, err := vmenv.Call(
		sender,
		address,
		input,
		cfg.GasLimit,
		cfg.Value,
	)

	return ret, leftOverGas, err
}
