SD_BUS_MESSAGE_SEAL(3) sd_bus_message_seal SD_BUS_MESSAGE_SEAL(3)
NAME
sd_bus_message_seal - Prepare a D-Bus message for transmission
SYNOPSIS
#include <systemd/sd-bus.h>
int sd_bus_message_seal(sd_bus_message *m, uint64_t cookie,
uint64_t timeout_usec);
DESCRIPTION
sd_bus_message_seal() finishes the message m and prepares it for
transmission using sd_bus_send(3). cookie specifies the identifier
used to match the message reply to its corresponding request.
timeout_usec specifies the maximum time in microseconds to wait for a
reply to arrive.
Note that in most scenarios, it's not necessary to call this function
directly. sd_bus_call(3), sd_bus_call_async(3) and sd_bus_send(3) will
seal any given messages if they have not been sealed yet.
RETURN VALUE
On success, this function returns a non-negative integer. On failure,
it returns a negative errno-style error code.
Errors
Returned errors may indicate the following problems:
-EINVAL
The m parameter is NULL.
-EBADMSG
The D-Bus message m has open containers.
-ENOMSG
The D-Bus message m is a reply but its type signature does not
match the return type signature of its corresponding member in the
object vtable.
NOTES
Functions described here are available as a shared library, which can
be compiled against and linked to with the libsystemd pkg-config(1)
file.
The code described here uses getenv(3), which is declared to be not
multi-thread-safe. This means that the code calling the functions
described here must not call setenv(3) from a parallel thread. It is
recommended to only do calls to setenv() from an early phase of the
program when no other threads have been started.
