ИМЯ

       sd_bus_pending_method_calls - Return the number of currently
       pending, outgoing method calls

СИНТАКСИС

       #include <systemd/sd-bus.h>

       int sd_bus_pending_method_calls(sd_bus *bus);

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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.

ПРИМЕЧАНИЯ

       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.

ИСТОРИЯ ИЗМЕНЕНИЙ

       sd_bus_pending_method_calls() was added in version 257.
