NAME
sd_bus_message_copy - Copy the contents of one message to another
SYNOPSIS
#include <systemd/sd-bus.h>
int sd_bus_message_copy(sd_bus_message **/m/, sd_bus_message */source/, int all);*
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.
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.
