/**
* g_pollable_input_stream_read_nonblocking:
* @stream: a #GPollableInputStream
* @buffer: a buffer to read data into (which should be at least @count
* bytes long).
* @count: the number of bytes you want to read
* @cancellable: (allow-none): a #GCancellable, or %NULL
* @error: #GError for error reporting, or %NULL to ignore.
*
* Attempts to read up to @count bytes from @stream into @buffer, as
* with g_input_stream_read(). If @stream is not currently readable,
* this will immediately return %G_IO_ERROR_WOULD_BLOCK, and you can
* use g_pollable_input_stream_create_source() to create a #GSource
* that will be triggered when @stream is readable.
*
* Note that since this method never blocks, you cannot actually
* use @cancellable to cancel it. However, it will return an error
* if @cancellable has already been cancelled when you call, which
* may happen if you call this method after a source triggers due
* to having been cancelled.
*
* Virtual: read_nonblocking
* Returns: the number of bytes read, or -1 on error (including
* %G_IO_ERROR_WOULD_BLOCK).
