SYNOPSIS        top

#include <systemd/sd-bus.h>int sd_bus_pending_method_calls(sd_bus *bus);

DESCRIPTION        top

sd_bus_pending_method_calls()returns the number of currently       pending outgoing method calls, i.e. method calls enqueued withsd_bus_call_async(3) for which no reply has been received yet, and       which have not reached a timeout yet.       Thebus argument may beNULL, in which case zero is returned.

RETURN VALUE        top

       This function returns 0 if there are no pending method calls, or aNULLbus 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.

NOTES        top

       Functions described here are available as a shared library, which       can be compiled against and linked to with thelibsystemd pkg-config(1) file.       The code described here usesgetenv(3), which is declared to be       not multi-thread-safe. This means that the code calling the       functions described here must not callsetenv(3) from a parallel       thread. It is recommended to only do calls tosetenv()from an       early phase of the program when no other threads have been       started.

HISTORY        top

sd_bus_pending_method_calls()was added in version 257.
