11 int sd_bus_message_copy(sd_bus_message *m, sd_bus_message *source,
12 int all);
13
15 sd_bus_message_copy() copies the contents from message source to m. If
16 all is false, a single complete type is copied (basic or container). If
17 all is true, the contents are copied until the end of the currently
18 open container or the end of source.
19
21 On success, this call returns true if anything was copied, and false if
22 there was nothing to copy. On failure, it returns a negative
23 errno-style error code.
