fill_async

Description:

public virtual async ssize_t fill_async (ssize_t count, int io_priority = DEFAULT, Cancellable? cancellable = null) throws Error

Reads data into this's buffer asynchronously, up to count size.

io_priority can be used to prioritize reads. For the synchronous version of this function, see fill.

If count is -1 then the attempted read size is equal to the number of bytes that are required to fill the buffer.

this	a BufferedInputStream
count	the number of bytes that will be read from the stream
io_priority	the I/O priority of the request
cancellable	optional Cancellable object
callback	a TaskReadyCallback
user_data	a pointer
