NAME         top

       sd_journal_get_usage - Journal disk usage

SYNOPSIS         top

       #include <systemd/sd-journal.h>

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

DESCRIPTION         top

       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         top

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

NOTES         top

       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.

HISTORY         top

       sd_journal_get_usage() was added in version 190.
