## Description

`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.

## Return Value

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.
