The value can be used only with the han- dle specified by h and objects associated with h. The scf_value_reset() function resets the value to the uninitialized state. The scf_value_destroy() function deallocates the object. The scf_value_type() function retrieves the type of the contents of v. The scf_value_is_type() function determines if a value is of a par- ticular type or any of its subtypes. The scf_type_base_type() function returns the base type of type. The scf_value_base_type() function returns the true base type of the value (the highest type reachable from the value's type). Type Identifier Base Type Type Description SCF_TYPE_INVALID reserved invalid type SCF_TYPE_BOOLEAN single bit SCF_TYPE_COUNT unsigned 64-bit quantity SCF_TYPE_INTEGER signed 64-bit quantity SCF_TYPE_TIME signed 64-bit seconds, signed 32-bit nanoseconds in the range 0 <= ns < 1,000,000,000 SCF_TYPE_ASTRING 8-bit NUL-terminated string SCF_TYPE_OPAQUE opaque 8-bit data SCF_TYPE_USTRING ASTRING 8-bit UTF-8 string SCF_TYPE_URI USTRING a URI string SCF_TYPE_FMRI URI a Fault Management Resource Identifier SCF_TYPE_HOST USTRING either a hostname, IPv4 address, or IPv6 address SCF_TYPE_HOSTNAME HOST a fully-qualified domain name SCF_TYPE_NETADDR_V4 HOST adotted-quad IPv4 address with optional network portion SCF_TYPE_NETADDR_V6 HOST legal IPv6 address The scf_value_get_boolean(), scf_value_get_count(), scf_value_get_integer(), scf_value_get_time(), scf_value_get_astring(), scf_value_get_ustring(), and scf_value_get_opaque() functions read a particular type of value from v. The scf_value_get_as_string() and scf_value_get_as_string_typed() functions convert the value to a string form. For scf_value_get_as_string_typed(), the value must be a reachable subtype of type. The scf_value_set_boolean(), scf_value_set_count(), scf_value_set_integer(), scf_value_set_time(), scf_value_set_astring(), scf_value_set_ustring(), and scf_value_set_opaque() functions set v to a particular value of a particular type. The scf_value_set_from_string() function is the inverse of scf_value_get_as_string(). It sets v to the value encoded in buf of type type. Upon successful completion, scf_value_create() returns a new, reset scf_value_t. Otherwise, it returns NULL. Upon successful completion, scf_value_handle() returns the handle associated with v. Otherwise, it returns NULL. The scf_value_base_type() function returns the base type of the value, or SCF_TYPE_INVALID on failure. Upon successful completion, scf_value_type() returns the type of the value. Otherwise, it returns SCF_TYPE_INVALID. Upon successful completion, scf_value_is_type(), scf_value_get_boolean(), scf_value_get_count(), scf_value_get_integer(), scf_value_get_time(), scf_value_set_time(), scf_value_set_from_string(), scf_value_set_astring(), scf_value_set_ustring(), and scf_value_set_opaque() return 0. Otherwise, they return -1. Upon successful completion, scf_value_get_astring(), scf_value_get_ustring(), scf_value_get_as_string(), and scf_value_get_as_string_typed() return the length of the string written, not including the terminating null byte. Otherwise, they return -1. Upon successful completion, scf_value_get_opaque() returns the number of bytes written. Otherwise, it returns -1. The scf_value_create() function will fail if: SCF_ERROR_INVALID_ARGUMENT The handle is NULL. SCF_ERROR_NO_MEMORY There is not enough memory to allocate an scf_value_t. The scf_value_handle() function will fail if: SCF_ERROR_HANDLE_DESTROYED The handle associated v has been destroyed. The scf_value_set_time() function will fail if: SCF_ERROR_INVALID_ARGUMENT The nanoseconds field is not in the range 0 <= ns < 1,000,000,000. The scf_type_base_type() function will fail if: SCF_ERROR_INVALID_ARGUMENT The type argument is not a valid type. The scf_value_set_astring(), scf_value_set_ustring(), scf_value_set_opaque(), and scf_value_set_from_string() functions will fail if: SCF_ERROR_INVALID_ARGUMENT The in argument is not a valid value for the specified type or is longer than the maximum supported value length. The scf_type_base_type(), scf_value_is_type(), and scf_value_get_as_string_typed() functions will fail if: SCF_ERROR_INVALID_ARGUMENT The type argument is not a valid type. The scf_value_type(), scf_value_base_type(), scf_value_get_boolean(), scf_value_get_count(), scf_value_get_integer(), scf_value_get_time(), scf_value_get_astring(), scf_value_get_ustring(), scf_value_get_as_string(), andscf_value_get_as_string_typed() functions will fail if: SCF_ERROR_NOT_SET The v argument has not been set to a value. The scf_value_get_boolean(), scf_value_get_count(), scf_value_get_integer(), scf_value_get_time(), scf_value_get_astring(), scf_value_get_ustring(), and scf_value_get_as_string_typed() functions will fail if: SCF_ERROR_TYPE_MISMATCH The requested type is not the same as the value's type and is not in the base-type chain. The scf_error(3SCF) function can be used to retrieve the error value.
