Invokes block when it will be possible to write at least min bytes providing byte buffer to it so lambda can write to the buffer up to ByteBuffer.remaining bytes. If there are no min bytes spaces available then the invocation could suspend until the requirement will be met.
Warning: it is not guaranteed that all of remaining bytes will be represented as a single byte buffer eg: it could be 4 bytes available for write but the provided byte buffer could have only 2 remaining bytes: in this case you have to invoke write again (with decreased min accordingly).
min - amount of bytes available for write, should be positive
block - to be invoked when at least min bytes free capacity available
