Thank you your sample code! I
Thank you for your reply! And thank you for your source code! I try to study by
your code.
Your buffer points to nothing, allocate an `array[4, byte]` and pass its
address to readBuffer.
I suggest you use streams if you need to save your position/restart your
processing.
For example this is [how I read the first 6
Here is my code that reads wave files:
[https://github.com/treeform/euphony/blob/master/src/euphony/wav.nim](https://github.com/treeform/euphony/blob/master/src/euphony/wav.nim)
There i use newFileStream which makes reading binary files really easy. Just

I want to read binary file inNim-language. Because I want to work with WAV
files.
But I don't know how easy it is to read the first four bytes. This may be
because I am not good at English.
I wrote the following code. However, nil is displayed.
var hFile = open("example.wav",
