ccs_result_t	ccs_create_features (ccs_feature_space_t feature_space, size_t num_values, ccs_datum_t values, ccs_features_t features_ret)
	Create a new instance of a features on a given feature space.

Detailed Description

A features is a binding (see binding.h) over a feature space (see feature_space.h).

Function Documentation

ccs_result_t ccs_create_features	(	ccs_feature_space_t	feature_space,
		size_t	num_values,
		ccs_datum_t *	values,
		ccs_features_t *	features_ret
	)

extern

Create a new instance of a features on a given feature space.

If no values are provided the values will be initialized to CCS_DATA_TYPE_NONE.

Parameters

[in]	feature_space
[in]	num_values	the number of provided values to initialize the features instance
[in]	values	an optional array of values to initialize the features
[out]	features_ret	a pointer to the variable that will hold the newly created features

Returns: CCS_RESULT_SUCCESS on success; CCS_RESULT_ERROR_INVALID_OBJECT if features is not a valid CCS feature space; CCS_RESULT_ERROR_INVALID_VALUE if features_ret is NULL; or if values is NULL and num_values is greater than 0; or if the number of values provided is not equal to the number of parameters in the feature space; CCS_RESULT_ERROR_OUT_OF_MEMORY if there was a lack of memory to allocate the new features

ccs_result_t ccs_features_get_feature_space	(	ccs_features_t	features,
		ccs_feature_space_t *	feature_space_ret
	)

extern

Get the associated feature space.

Parameters

[in]	features
[out]	feature_space_ret	a pointer to the variable that will contain the feature space

Returns: CCS_RESULT_SUCCESS on success; CCS_RESULT_ERROR_INVALID_OBJECT if features is not a valid CCS features; CCS_RESULT_ERROR_INVALID_VALUE if feature_space_ret is NULL
