( https://gerrit.osmocom.org/13575 Change subject: add OSMO_IMSI_SIZE ...................................................................... add OSMO_IMSI_SIZE Various places in our code base figure out how many char they need to safely store an IMSI. An IMSI can have a checksum digit, which is not reflected by GSM23003_IMSI_MAX_DIGITS. And we usually needs a terminating \0. Instead of having a magic +2 repeated every so often, rather define OSMO_IMSI_SIZE to contain both checksum digit and nul char, and have the explanatory comment with it here in libosmocore.
