Description sd_bus_call_method() is a convenience function for calling a D-Bus method. It combines the sd_bus_message_new_method_call3, sd_bus_message_append3 and sd_bus_call3 functions into a single function call. sd_bus_call_method_async() is a convenience function for calling a D-Bus method asynchronously. It combines the sd_bus_message_new_method_call3, sd_bus_message_append3 and sd_bus_call_async3 functions into a single function call. Return Value On success, these functions returns 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_call3, sd_bus_message_append3, sd_bus_call3 and sd_bus_call_async3 for a list of possible errors.
