On success, this function returns a non-negative integer. On failure, it returns a negative errno-style error code.Errors
Returned errors may indicate the following problems: -EINVALThe input parameter call is
NULL.
Message call is not a method call message.
Message call is not attached to a bus.
Message m is not a method reply message.
-EPERM
Message call has been sealed.
-ENOTCONN
The bus to which message call is
attached is not connected.
-ENOMEM
Memory allocation failed.
In addition, any error returned by sd_bus_send(1) may be returned.
