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.
The sd_journal_get_usage() interface is
available as a shared library, which can be compiled and linked to
with the
libsystemd pkg-config(1)
file.
