NAME
scf_snapshot_create, scf_snapshot_handle, scf_snapshot_destroy, scf_snapshot_get_parent, scf_snapshot_get_name, scf_snapshot_update, scf_instance_get_snapshot - create and manipulate snapshot handles and snapshots in the Service Configuration Facility SYNOPSIS
cc [ flag... ] file... -lscf [ library... ] #include <libscf.h> scf_snapshot_t *scf_snapshot_create(scf_handle_t *handle); scf_handle_t *scf_snapshot_handle(scf_snapshot_t *snap); void scf_snapshot_destroy(scf_snapshot_t *snap); int scf_snapshot_get_parent(const scf_snapshot_t *snap, scf_instance_t *inst); ssize_t scf_snapshot_get_name(const scf_snapshot_t *snap, char *buf, size_t size); int scf_snapshot_update(scf_snapshot_t *snap); int scf_instance_get_snapshot(const scf_instance_t *inst, const char *name, scf_snapshot_t *snap); A snapshot is an unchanging picture of the full set of property groups associated with an instance. Snapshots are automatically created and managed by the Solaris Management Facility. See smf(5). A snapshot consists of a set of snaplevels, each of which holds copies of the property groups associated with an instance or service in the resolution path of the base instance. Typically, there is one snaplevel for the instance and one for the instance's parent service. The scf_snapshot_create() function allocates and initializes a new scf_snapshot_t bound to handle. The scf_snapshot_destroy() function destroys and frees snap. The scf_snapshot_handle() function retrieves the handle to which snap is bound. The scf_snapshot_get_parent() function sets inst to the parent of the snapshot to which snap is set. The scf_snapshot_get_name() function retrieves the name of the snapshot to which snap is set. The scf_snapshot_update() function reattaches snap to the latest version of the snapshot to which snap is set. The scf_instance_get_snapshot() function sets snap to the snapshot specified by name in the instance specified by inst. To walk all of the snapshots, see scf_iter_instance_snapshots(3SCF). To access the snaplevels of a snapshot, see scf_snapshot_get_base_snaplevel(3SCF). Upon successful completion, scf_snapshot_create() returns a new scf_snapshot_t. Otherwise, it returns NULL. Upon successful completion, scf_snapshot_handle() returns the handle to which snap is bound. Otherwise, it returns NULL. Upon successful completion, scf_snapshot_get_name() returns the length of the string written, not including the terminating null byte. Oth- erwise, it returns NULL. The scf_snapshot_update() function returns 1 if the snapshot was updated, 0 if the snapshot had not been updated, and -1 on failure. Upon successful completion, scf_snapshot_get_parent() and scf_instance_get_snapshot() return 0. Otherwise, they return -1. The scf_snapshot_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_snapshot_t. SCF_ERROR_NO_RESOURCES The server does not have adequate resources for a new instance handle. The scf_snapshot_handle() function will fail if: SCF_ERROR_HANDLE_DESTROYED The handle associated with snap has been destroyed. The scf_snapshot_get_name() and scf_snapshot_get_parent() functions will fail if: SCF_ERROR_DELETED The snapshot has been deleted. SCF_ERROR_NOT_SET The snapshot is not set. SCF_ERROR_NOT_BOUND The handle is not bound. SCF_ERROR_CONNECTION_BROKEN The connection to the repository was lost. The scf_snapshot_update() function will fail if: SCF_ERROR_DELETED An ancestor of the snapshot specified by snap has been deleted. SCF_ERROR_NOT_SET The snapshot specified by snap is not set. SCF_ERROR_NOT_BOUND The handle is not bound. SCF_ERROR_CONNECTION_BROKEN The connection to the repository was lost. SCF_ERROR_INVALID_ARGUMENT The snap argument refers to an invalid scf_snapshot_t. The scf_instance_get_snapshot() function will fail if: SCF_ERROR_DELETED The instance has been deleted. SCF_ERROR_NOT_SET The instance is not set. SCF_ERROR_NOT_FOUND The snapshot specified by name was not found. SCF_ERROR_INVALID_ARGUMENT The value of the name argument is not a valid snapshot name. SCF_ERROR_HANDLE_MISMATCH The instance and snapshot are not derived from the same handle. SCF_ERROR_NOT_BOUND The handle is not bound. SCF_ERROR_CONNECTION_BROKEN The connection to the repository was lost. The scf_error(3SCF) function can be used to retrieve the error value.
