nabto_device_set_log_callback()

DESCRIPTION

Set log callback if custom logging is desired. The log callback is stored globally, and so, the device reference is unused. This also means if multiple Nabto Device instances is running in the same process, this function configures the callback for all instances. Since the device reference is unused, this function can be called before nabto_device_new() to enable logging of module initialization, particularly useful when integrating a new embedded platform.

The log callback can be removed by setting the callback and data to NULL.
