SD_BUS_MESSAGE_REWIND(3) sd_bus_message_rewind SD_BUS_MESSAGE_REWIND(3)
sd_bus_message_rewind - Return to beginning of message or current
container
#include <systemd/sd-bus.h>
int sd_bus_message_rewind(sd_bus_message *m, int complete);
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.
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:
-EINVAL
The m parameter is NULL.
-EPERM
The message m has not been sealed.
These APIs are implemented as a shared library, which can be
compiled and linked to with the libsystemd pkg-config(1) file.
