NAME

6       sd_bus_message_copy - Copy the contents of one message to another
7

SYNOPSIS

9       #include <systemd/sd-bus.h>
10
11       int sd_bus_message_copy(sd_bus_message *m, sd_bus_message *source,
12                               int all);
13

DESCRIPTION

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

RETURN VALUE

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.
