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