Reading/Writing files in CP/M

[under4mhz]

Does anyone have some code on reading and writing files under CP/M?

I found a fairly descriptive manual: Section 5 CP/M 2 System Interface, but ever since stackoverflow was created, I haven't the patience to reverse engineer manuals anymore.

Actually, that might be a good stackoverflow question and I can get some more dopamine, er, points.

Does the attached help?

That gives me a good overview of how cpm works.

From that I was able to find https://github.com/tstih/libcpm3-z80, which seems to implemented an open/close C interface which is what I was hoping for.
