laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/20204 ) Change subject: add osmo_use_count_to_str_c() ...................................................................... add osmo_use_count_to_str_c() So far there is only osmo_use_count_name_buf(). Also provide a use count to string using a talloc context, allowing to use OTC_SELECT. - instead of foo_name(), rather use foo_to_str(). - osmo_use_count_name_buf() returns the buf and not the chars_needed. So add osmo_use_count_to_str_buf() with a signature that is usable by OSMO_NAME_C_IMPL(). - provide osmo_use_count_to_str_c() using OSMO_NAME_C_IMPL().
