NAME         top

       sd_bus_message_copy - Copy the contents of one message to another

SYNOPSIS         top

       #include <systemd/sd-bus.h>

       int sd_bus_message_copy(sd_bus_message *m,
                               sd_bus_message *source, int all);

DESCRIPTION         top

       sd_bus_message_copy() copies the contents from message source to
       m. If all is false, a single complete type is copied (basic or
       container). If all is true, the contents are copied until the end
       of the currently open container or the end of source.

RETURN VALUE         top

       On success, this call returns true if anything was copied, and
       false if there was nothing to copy. On failure, it returns a
       negative errno-style error code.

   Errors
       Returned errors may indicate the following problems:

       -EINVAL
           source or m are NULL.

       -EPERM
           Message m has been sealed or source has not been sealed.

       -ESTALE
           Destination message is in invalid state.

       -ENXIO
           Destination message cannot be appended to.

       -ENOMEM
           Memory allocation failed.

NOTES         top

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