Similarly, sd_bus_service_name_is_valid() checks if the argument is a valid bus service name, sd_bus_member_name_is_valid() checks if the argument is a valid bus interface member name, and sd_bus_object_path_is_valid() checks if the argument is a valid bus object path. Those functions generally check that only allowed characters are used and that the length of the string is within limits. Those functions return 1 if the argument is a valid interface / service / member name or object path, and 0 if it is not. If the argument is NULL, an error is returned. Returned errors may indicate the following problems: -EINVAL The p parameter is NULL. sd_bus_interface_name_is_valid(), sd_bus_service_name_is_valid(), sd_bus_member_name_is_valid(), and sd_bus_object_path_is_valid() were added in version 246. systemd1, sd-bus3, sd_bus_call_method3
