Function Documentation

config_get_level()

int config_get_level

(

config_t const *

config

)

Returns the compression level specified by the config, or CONFIG_NO_LEVEL if no level is specified. Note that 0 is a valid compression level, meaning default.

config_get_zstd_params()

ZSTD_parameters config_get_zstd_params	(	config_t const *	config,
		uint64_t	srcSize,
		size_t	dictSize )

Returns the compression parameters specified by the config.

config_skip_data()

int config_skip_data	(	config_t const *	config,
		data_t const *	data )

Returns true if the config should skip this data. For instance, if the config requires a dictionary but the data doesn't have one.

Variable Documentation

configs

config_t const* const* configs = g_configs

The NULL-terminated list of configs.
