14 sd_journal_get_usage() determines the total disk space currently used
15 by journal files (in bytes). If SD_JOURNAL_LOCAL_ONLY was passed when
16 opening the journal, this value will only reflect the size of journal
17 files of the local host, otherwise of all hosts.

20 sd_journal_get_usage() returns 0 on success or a negative errno-style
21 error code.

24 All functions listed here are thread-agnostic and only a single
25 specific thread may operate on a given object during its entire
26 lifetime. It's safe to allocate multiple independent objects and use
27 each from a specific thread in parallel. However, it's not safe to
28 allocate such an object in one thread, and operate or free it from any
29 other, even if locking is used to ensure these threads don't operate on
30 it at the very same time.
31
32 Functions described here are available as a shared library, which can
33 be compiled against and linked to with the libsystemd pkg-config(1)
34 file.
