#include <tinynotify-systemwide.h> extern const NotifyError NOTIFY_ERROR_SYSCALL_FAILED; extern const NotifyError NOTIFY_ERROR_UIDS_COMPROMISED; extern const NotifyError NOTIFY_ERROR_NO_BUS_FOUND; int notification_send_systemwide (Notification notification
,NotifySession session
);
The libtinynotify-systemwide helper library provides the routines to send notifications system-wide, i.e. on all D-Bus session buses in the system.
Using it as basically as simple as adding the necessary include,
and replacing notification_send()
in the code with
notification_send_systemwide()
.
Although libtinynotify-cli links with the actual libtinynotify itself, and uses its header, one should refer to the libtinynotify pkg-config package explicitly and include its header anyway.
extern const NotifyError NOTIFY_ERROR_SYSCALL_FAILED;
notification_send_systemwide* An error raised when one of the syscalls required for the operation fails.
extern const NotifyError NOTIFY_ERROR_UIDS_COMPROMISED;
An error raised when setresuid()
fails to restore the original caller UID.
This means that the application has lost its original UID and should terminate ASAP.
extern const NotifyError NOTIFY_ERROR_NO_BUS_FOUND;
An error returned by notification_send_systemwide()
when it was unable
to find a single D-Bus session bus in procfs.
Please note that this as well covers a case when the session bus is not visible to user in procfs due to limited privileges.
int notification_send_systemwide (Notification notification
,NotifySession session
);
Send a notification to all notification daemons found (in procfs).
Todo: support formatstring args.
