sd_bus_pending_method_calls - Return the number of currently pending, outgoing method calls
Contents
Description
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.
History
sd_bus_pending_method_calls() was added in version 257.
Name
sd_bus_pending_method_calls - Return the number of currently pending, outgoing method calls
Notes
Functions described here are available as a shared library, which can be compiled against and linked to
with the libsystemdpkg-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.
Return Value
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.
