sd_journal_get_usage - Journal disk usage
#include <systemd/sd-journal.h>
int sd_journal_get_usage(sd_journal *j, uint64_t *bytes);
sd_journal_get_usage() determines the total disk space currently used
by journal files (in bytes). If SD_JOURNAL_LOCAL_ONLY was passed when
opening the journal, this value will only reflect the size of journal
files of the local host, otherwise of all hosts.
sd_journal_get_usage() returns 0 on success or a negative errno-style
error code.
All functions listed here are thread-agnostic and only a single
specific thread may operate on a given object during its entire
lifetime. It's safe to allocate multiple independent objects and use
each from a specific thread in parallel. However, it's not safe to
allocate such an object in one thread, and operate or free it from
any other, even if locking is used to ensure these threads don't
operate on it at the very same time.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
