Имя (Name)

sd_bus_message_copy - Copy the contents of one message to another

---

Синопсис (Synopsis)

#include <systemd/sd-bus.h>

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

---

Описание (Description)

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.

---

Возвращаемое значение (Return value)

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.
