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.

       Returned errors may indicate the following problems:

           source or m are NULL.

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

           Destination message is in invalid state.

           Destination message cannot be appended to.

           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.
