sd_bus_call_method() is a convenience function for initializing a bus
message object and calling the corresponding D-Bus method. It
combines the sd_bus_message_new_method_call(3),
sd_bus_message_append(3) and sd_bus_call(3) functions into a single
function call.
sd_bus_call_method_async() is a convenience function for initializing
a bus message object and calling the corresponding D-Bus method
asynchronously. It combines the sd_bus_message_new_method_call(3),
sd_bus_message_append(3) and sd_bus_call_async(3) functions into a
single function call.
On success, these functions return a non-negative integer. On
failure, they return a negative errno-style error code.
Errors
See the man pages of sd_bus_message_new_method_call(3),
sd_bus_message_append(3), sd_bus_call(3) and sd_bus_call_async(3) for
a list of possible errors.
These APIs are implemented as a shared library, which can be compiled
and linked to with the libsystemd pkg-config(1) file.
