SD_BUS_...OD_CALLS(3) sd_bus_pending_method_calls SD_BUS_...OD_CALLS(3)
sd_bus_pending_method_calls - Return the number of currently
pending, outgoing method calls
#include <systemd/sd-bus.h>
int sd_bus_pending_method_calls(sd_bus *bus);
sd_bus_pending_method_calls() returns the number of currently
pending outgoing method calls, i.e. method calls enqueued with
sd_bus_call_async(3) for which no reply has been received yet,
and which have not reached a time-out yet.
The bus argument may be NULL, in which case zero is returned.
This function returns 0 if there are no pending method calls, or
a NULL bus object was specified. On failure, a negative
errno-style error code is returned.
Errors
Returned errors may indicate the following problems:
-ECHILD
The bus connection has been created in a different process,
library or module instance.
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.
sd_bus_pending_method_calls() was added in version 257.
