set_writer_func


Description:

[ Version ( since = "2.50" ) ]
public void set_writer_func (owned LogWriterFunc func)

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 ( 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.

Parameters:

func

log writer function, which must not be null

user_data

user data to pass to func

user_data_free

function to free user_data once it’s finished with, if non-null
