Declaration
GLogWriterOutput
g_log_writer_journald (
GLogLevelFlags log_level,
const GLogField* fields,
gsize n_fields,
gpointer user_data
)
Description
Format a structured log message and send it to the systemd journal as a set of key–value pairs.
All fields are sent to the journal, but if a field has length zero (indicating program-specific data) then only its key will be sent.
This is suitable for use as a GLogWriterFunc.
If GLib has been compiled without systemd support, this function is still
defined, but will always return GLogWriterOutput.
Available since: 2.50
