NAME

6       sd_bus_message_rewind - Return to beginning of message or current
7       container
8

SYNOPSIS

10       #include <systemd/sd-bus.h>
11
12       int sd_bus_message_rewind(sd_bus_message *m, int complete);
13

DESCRIPTION

15       sd_bus_message_rewind() moves the "read pointer" in the message m to
16       either the beginning of the message (if complete is true) or to the
17       beginning of the currently open container. If no container is open,
18       complete has no effect.
19

RETURN VALUE

21       On success, this function returns 0 or a positive integer. The value is
22       zero if the current container or whole message in case no container is
23       open is empty, and positive otherwise. On failure, it returns a
24       negative errno-style error code.
25
26   Errors
27       Returned errors may indicate the following problems:
28
29       -EINVAL
30           The m parameter is NULL.
31
32       -EPERM
33           The message m has not been sealed.
