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.
