Title: Reading/Writing Files, Listing Directories
Post by: SirCmpwn on December 12, 2010, 10:29:50 pm: Hello,
How do I do all of the above?
Title: Re: Reading/Writing Files, Listing Directories
Post by: jnesselr on December 12, 2010, 10:31:23 pm: In C. There are functions to read and write files (fwrite I think).

For directories, try this:

EDIT: http://en.wikipedia.org/wiki/C_file_input/output for reading and writing.

The directory example uses dir.h, which is not available for download anywhere nearby.

I see. IIRC, you open the file, and read it. Haven't done that in a while. I know you open it, read the file, and then close it. Not sure otherwise.

Lol, sorry. It's platform specific, IIRC, so you are best off using a methods within #ifdef (Wait, that's C right?) based on the OS. So, yeah, not exactly sure. I've done it before, but only when writing a stream to a log file, and that was a year ago, so I don't fully remember.

That could work. Wait, is this for NSpire coding? Oh, I have no idea, then.

Post by: apcalc on December 12, 2010, 11:07:34 pm: You might want to look at the source for either bwang's bmpviewer or critor's ndshell. Both of those programs use file listing. I have never used this, so I won't be of any help for this (although, I better learn soon, as it will probably be used in Chip's Challenge ;))

Post by: SirCmpwn on December 12, 2010, 11:08:53 pm: I would like to look at ndshell, where do I download it? The tibank forum doesn't have a download link.
