The size passed to snprintf() includes the space for the trailing space. So there is no reason here not to use all the available space. So remove the -1 when computing 'name_len'. While at it, use the size of the array directly instead of the intermediate 'name_len' variable. snprintf() also guaranties that the buffer if NULL terminated, so there is no need to write an additional trailing NULL "To be sure".
