) -> i32
Calls a contract by its package hash. Optionally accepts a serialized Option<u32>
as a
version that for None
case would call most recent version for given protocol version,
otherwise it selects a specific contract version. Requires an entry point name
registered in a given version of contract. Returns a standard error code in case of
failure, otherwise a successful execution returns zero. Bytes returned from contract
execution are set to result_size
pointer
