NAME¶

sd_bus_message_rewind - Return to beginning of message or current container

SYNOPSIS¶

#include <systemd/sd-bus.h>

int sd_bus_message_rewind(sd_bus_message *m, int complete);

DESCRIPTION¶

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.

NOTES¶

These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
