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.

   Errors
       Returned errors may indicate the following problems:

       -EINVAL
           The m parameter is NULL.

       -EPERM
           The message m has not been sealed.

NOTES

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