DESCRIPTION
The scf_entry_create() function allocates a new transaction entry han‐
dle. The scf_entry_destroy() function destroys the transaction entry
handle. The scf_error() function is not modified by this call.
The scf_entry_handle() function retrieves the handle associated with
entry.
A transaction entry represents a single action on a property in a prop‐
erty group. If an entry is added to a transaction using scf_transac‐
tion_property_new(3SCF), scf_transaction_property_change(3SCF), or
scf_transaction_property_change_type(3SCF), scf_entry_add_value() can
be called zero or more times to set up the set of values for that prop‐
erty. Each value must be set and of a compatible type to the type asso‐
ciated with the entry. When later retrieved from the property, the val‐
ues will have the type of the entry. If the values are committed suc‐
cessfully with scf_transaction_commit(3SCF), they will be set in the
order in which they were added with scf_entry_add_value().
The scf_entry_reset() function resets a transaction entry, disassociat‐
ing it from any transaction it is a part of (invalidating the transac‐
tion in the process), and disassociating any values that were added to
it.
The scf_entry_destroy_children() function destroys all values associ‐
ated with the transaction entry. The entry itself is not destroyed.
RETURN VALUES
Upon successful completion, scf_entry_create() returns a new scf_trans‐
action_entry_t. Otherwise, it returns NULL.
Upon successful completion, scf_entry_handle() returns the handle asso‐
ciated with the transaction entry. Otherwise, it returns NULL.
Upon successful completion, scf_entry_add_value() returns 0. Otherwise,
it returns -1.
ERRORS
The scf_entry_create() function will fail if:
SCF_ERROR_INVALID_ARGUMENT The handle argument is NULL.
SCF_ERROR_NO_MEMORY There is not enough memory to allocate an
scf_transaction_entry_t.
The scf_entry_handle() function will fail if:
SCF_ERROR_HANDLE_DESTROYED The handle associated with entry has been
destroyed.
The scf_entry_add_value() function will fail if:
SCF_ERROR_HANDLE_MISMATCH The value and entry arguments are not
derived from the same handle.
SCF_ERROR_IN_USE The value has been added to another
entry.
SCF_ERROR_INTERNAL An internal error occurred.
SCF_ERROR_INVALID_ARGUMENT The value argument is not set, or the
entry was added to the transaction using
scf_transaction_property_delete(3SCF).
SCF_ERROR_NOT_SET The transaction entry is not associated
with a transaction.
SCF_ERROR_TYPE_MISMATCH The type of the value argument does not
match the type that was set using
scf_transaction_property_new(),
scf_transaction_property_change(), or
scf_transaction_property_change_type().
The scf_error(3SCF) function can be used to retrieve the error value.
