sd_journal_has_runtime_files() returns a positive value if runtime
journal files (present in /run/systemd/journal/) have been found.
Otherwise returns 0.
sd_journal_has_persistent_files() returns a positive value if
persistent journal files (present in /var/log/journal/) have been
found. Otherwise returns 0.
Both sd_journal_has_runtime_files() and
sd_journal_has_persistent_files() return -EINVAL if their argument is
NULL.
All functions listed here are thread-agnostic and only a single
thread may operate on a given sd_journal object.
Functions listed here are available as a shared library, which can be
compiled and linked to with the libsystemd pkg-config(1) file.
