    function check_auth_args(a_t: auth_type, args: byte_array, signers: list<byte_array>, required_flags: list<text>): validation_result
    source

    Checks that the multi-sig auth descriptor has all the requirements to authorize an operation.

    Can only be called from an operation.

    Gives invalid results when the signatures cannot be validated, i.e.:

    • signers is 0 or more than one, but the auth type is auth_type.S
    • the single sig signer did not sign
    • not enough multisig signers signed
    • the flags of the auth descriptors do not contain all required_flags

    Parameters

    • args — The args for this auth descriptor.
    • signers — The signers for this auth descriptor.
    • required_flags — The flags it must have for the operation that needs to be authorized.

    Returns

    utils.VALID if valid, utils.invalid otherwise.
