record_global_constant_storage_space ctxt size records paid storage space for registering a new global constant. Cost is <size> in bytes + 65 additional bytes for the key hash of the expression. Returns new context and the cost.

record_paid_storage_space ctxt contract updates the amount of storage consumed by the contract and considered as accounted for as far as future payment is concerned. Returns a new context, the total space consumed by the contract, and the additional (and unpaid) space consumed since the last call of this function on this contract.

check_storage_limit ctxt ~storage_limit raises the Storage_limit_too_high error iff storage_limit is negative or greater the constant hard_storage_limit_per_operation.

burn_storage_fees ctxt ~storage_limit ~payer consumed takes funds from the payer to pay the cost of the consumed storage. This function has an optional parameter ~origin that allows to set the origin of returned balance updates (by default the parameter is set to Block_application). Returns an updated context, an updated storage limit equal to storage_limit - consumed, and the relevant balance updates. Raises the Operation_quota_exceeded error if storage_limit < consumed. Raises the Cannot_pay_storage_fee error if the funds from the payer are not sufficient to pay the storage fees.

Calls burn_storage_fees with the parameter consumed mapped to the constant origination_size.
