sd_bus_message_rewind() moves the "read pointer" in the message m to either the beginning of the message (if complete is true) or to the beginning of the currently open container. If no container is open, complete has no effect.RETURN VALUE
On success, this function returns 0 or a positive integer. The value is zero if the current container or whole message in case no container is open is empty, and positive otherwise. On failure, it returns a negative errno-style error code.Errors
Returned errors may indicate the following problems: -EINVALThe m parameter is NULL.
-EPERM
The message m has not been
sealed.
