- create and manipulate transaction in the Service Configuration Facility
cc [ flag… ] file… -lscf [ library… ] #include <libscf.h> scf_transaction_entry_t *scf_entry_create(scf_handle_t *handle);
scf_handle_t *scf_entry_handle(scf_transaction_entry_t *entry);
void scf_entry_destroy(scf_transaction_entry_t *entry);

The scf_entry_create() function allocates a new transaction entry handle. The scf_entry_destroy() function destroys the transaction entry handle.
The scf_entry_handle() function retrieves the handle associated with entry.
A transaction entry represents a single action on a property in a property group. If an entry is added to a transaction using scf_transaction_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 property. Each value must be set and of a compatible type to the type associated with the entry. When later retrieved from the property, the values will have the type of the entry. If the values are committed successfully 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, disassociating it from any transaction it is a part of (invalidating the transaction in the process), and disassociating any values that were added to it.
The scf_entry_destroy_children() function destroys all values associated with the transaction entry. The entry itself is not destroyed.
Upon successful completion, scf_entry_create() returns a new scf_transaction_entry_t. Otherwise, it returns NULL.
Upon successful completion, scf_entry_handle() returns the handle associated with the transaction entry. Otherwise, it returns NULL.
Upon successful completion, scf_entry_add_value() returns 0. Otherwise, it returns -1.
The scf_entry_create() function will fail if:
The handle argument is NULL.
There is not enough memory to allocate an scf_transaction_entry_t.
The scf_entry_handle() function will fail if:
The handle associated with entry has been destroyed.
The scf_entry_add_value() function will fail if:
The value and entry arguments are not derived from the same handle.
The value has been added to another entry.
An internal error occurred.
The value argument is not set, or the entry was added to the transaction using scf_transaction_property_delete(3SCF).
The transaction entry is not associated with a transaction.
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.
