Description:

public async bool mail_signature_load (int io_priority, Cancellable? cancellable, out string contents, out size_t length) throws Error

this	an Source
io_priority	the I/O priority of the request
cancellable	optional Cancellable object, or `null`
callback	a TaskReadyCallback to call when the request is satisfied
user_data	data to pass to the callback function
