NAME
       sd_journal_get_usage - Journal disk usage

SYNOPSIS
       #include <systemd/sd-journal.h>

       int sd_journal_get_usage(sd_journal *j, uint64_t *bytes);

DESCRIPTION
       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.

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

NOTES
       All functions listed here are thread-agnostic and only a single thread
       may operate on a given object at any given time. Different threads may
       access the same object at different times. Multiple independent objects
       may be used from different threads in parallel.

       Functions described here are available as a shared library, which can
       be compiled against and linked to with the libsystemd pkg-config(1)
       file.
