I have a library that does all sorts of things and it only uses FILE_WRITE. Seems to be able to read and write no problem.
I'm working on this new piece of code and if I open with FILE_WRITE.. It only lets me write. If I try reading I get 0 bytes bytes read. If I open it with FILE_READ then it works. It also works if I just omit the READ WRITE thing all together.
What's the rules here? The reference documentation seems a little spotty for this stuff.
