Detailed Description

A feature space is a context (see context.h) defining a set of features represented using CCS parameters (see parameter.h).

Function Documentation

ccs_result_t ccs_create_feature_space	(	const char *	name,
		size_t	num_parameters,
		ccs_parameter_t *	parameters,
		ccs_feature_space_t *	feature_space_ret
	)

extern

Create a new feature space.

Parameters

[in]	name	pointer to a string that will be copied internally
[in]	num_parameters	the number of provided parameters
[in]	parameters	an array of `num_parameters` parameters to add to the feature space
[out]	feature_space_ret	a pointer to the variable that will hold the newly created feature space

Returns: CCS_RESULT_SUCCESS on success; CCS_RESULT_ERROR_INVALID_VALUE if name is NULL; or if feature_space_ret is NULL; or if parameters is NULL; or if num_parameters is NULL; CCS_RESULT_ERROR_INVALID_OBJECT if a parameter is not a valid CCS parameter; CCS_RESULT_ERROR_INVALID_PARAMETER if a parameter appears more than once in parameters; or if two or more parameters share the same name; or if a parameter is already part of another context; CCS_RESULT_ERROR_OUT_OF_MEMORY if there was a lack of memory to allocate the new feature space

ccs_result_t ccs_feature_space_get_default_features	(	ccs_feature_space_t	feature_space,
		ccs_features_t *	features_ret
	)

extern

Get the default features of a feature space.

Parameters

[in]	feature_space
[in]	features_ret	a pointer to a variable that will contain the returned features.

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