Reading Data from .MYD file

Hello, I having some problems trying to read the data from the .MYD file. I'm developing a program that needs to read the data directly from the file. I managed to read properly the .frm, but I'm struggling with the .myd. I read pretty much all the info from the internal manuals (https://dev.mysql.com/doc/internals/en/myisam.html).

So, I am wondering, how is it possible to know which column the data belongs to. My data is mostly mediumblob using dynamic file format, and I know that there is 3 bytes for the length of the blob and then the data itself. For example, if I have 10 columns, but only 2 of those are containing data, how do we know which column contains data from the .myd file?

Thank you.
