NAME SYNOPSIS DESCRIPTION RETURN VALUE Errors NOTES SEE ALSO

NAME

sd_bus_reply_method_return, sd_bus_reply_method_returnv − Reply to a D−Bus method call

SYNOPSIS

#include <elogind/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.

RETURN VALUE

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.
