НАЗВАНИЕ

       sd_bus_message_copy - Copy the contents of one message to another

СИНТАКСИС

       #include <systemd/sd-bus.h>

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

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       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.

ПРИМЕЧАНИЯ

       Functions described here are available as a shared library, which
       can be compiled against and linked to with the
       libsystemd pkg-config(1) file.

       The code described here uses getenv(3), which is declared to be
       not multi-thread-safe. This means that the code calling the
       functions described here must not call setenv(3) from a parallel
       thread. It is recommended to only do calls to setenv() from an
       early phase of the program when no other threads have been
       started.
