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

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