sd_bus_reply_method_return, sd_bus_reply_method_returnv - Reply to a D-Bus method call
#include <systemd/sd-bus.h> int sd_bus_reply_method_return(sd_bus_message *call, const char *types, ...); int sd_bus_reply_method_returnv(sd_bus_message *call, const char *types, va_list ap);
sd_bus_reply_method_return() sends a reply to the call message. The type string types and the arguments that follow it must adhere to the format described in sd_bus_message_append(3). If no reply is expected to call, this function succeeds without sending a reply.
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: -EINVAL The 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.
These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
