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, its 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
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd *pkg-config*(1) file.
