feed_eof()

Feed the buffer with end of file

read(n=-1, chunksize=None)

Read data from the buffer. Reads until eof or n bytes.

Parameters:n – The amount of data to read. Returns:A bytearray with the data

read_into(buffer, n, offset=0)

Read data from the buffer into a bytearray. Reads until eof or n bytes.

n must not exceed the buffer limit, or else it will block forever.

Parameters:

• buffer – The bytearray to write the data into.
• n – The amount of data to read.
• offset – The index into buffer to write to.

read_into_exactly(buffer, n, offset=0)

Read data from the buffer into a bytearray. Reads n bytes or throws an exception if reading eof.

n must not exceed the buffer limit, or else it will block forever.

Parameters:

• buffer – The bytearray to write the data into.
• n – The amount of data to read.

set_exception(exc)

Set an exception to raise at next read.

write(data)

Write some data to the buffer, length must not exceed the buffer limit, or else it will block forever.
