The decc$feature_get function allows you to call the decc$feature_get_value function with a character-string feature name, rather than an index into an internal C RTL table. On error, -1 is returned and errno is set to indicate the error. See also decc$feature_get_value, decc$feature_get_index, decc$feature_get_name, decc$feature_set, decc$feature_set_value, decc$feature_show, and decc$feature_show_all.
