NAME
sd_bus_message_seal - Prepare a D-Bus message for transmissionSYNOPSIS
#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: -EINVALThe 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.SEE ALSO
