logSetWriterFunc

Set a writer function which will be called to format and write out each log message.

Each program should set a writer function, or the default writer (func@GLib.log_writer_default) will be used.

Libraries must not call this function — only programs are allowed to install a writer function, as there must be a single, central point where log messages are formatted and outputted.

There can only be one writer function. It is an error to set more than one.
