sd_bus_pending_method_calls - Man Page

#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 timeout 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.

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.
