io.BytesIO

[Fabian von Romberg]

Hi Steven,


actually why I need is to know how much memory has been allocated for buffering.

getsizeof gets the size of the object structure.

For example, if I do io.BytesIO.truncate(10000), it will resize the buffer to 10000 bytes.  So my question is how to get those 10000 back from an attribute or method?

Regards,
Fabian
