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.
