libiio buffering

A few questions about libiio buffer handling:

 

Is iio_buffer_push() blocking?  Can it be configured for non-blocking with a callback upon completion?  How do I know when it is safe to refill a tx buffer?

 

Similarly on the rx side, can iio_buffer_refill() be wrapped with a call to select() to make non-blocking?  If I want to wait for a certain number of samples, can I query the number of bytes available?

 

Also, can a user allocated memory space be used as an iio_buffer?  For example, if I reserve a large chunk of physically contiguous memory by using the "mem=" kernel command line parameter, can that memory region be used as an iio_buffer?
