NAME         top

       sd_bus_message_rewind - Return to beginning of message or current

SYNOPSIS         top

       #include <systemd/sd-bus.h>

       int sd_bus_message_rewind(sd_bus_message *m, int complete);

DESCRIPTION         top

       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         top

       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.

       Returned errors may indicate the following problems:

           The m parameter is NULL.

           The message m has not been sealed.

NOTES         top

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