Actually this would be a non-uda format involving volume nrrds nested in a directory hierarchy (similarly to how uda's are organized).

It's true that uda/xml makes directory reading a bit easier; nonetheless I think readdir() will work.

if you're using this for UDA directories then you can avoid having to parse through directories as the index.xml file lists all the necessary files and locations relative to the root dir. Look in UDAReader.cc for the relevant code.

If it's part of the CSAFE scene or viewer I wouldn't worry about
portability beyond mac/linux. That code is all optional and can be
disabled on other platforms.

I suppose it could; however this would be for reading a special directory structure with nested volume data, and then reading that data into Manta. It would probably be easier to keep it C++ (although I agree file management is much cleaner in python!)

This is for mac and Linux (the platforms intended to run Carson's csafe demo), both of which are posix-compliant. I think Windows even has opendir/readdir equivalents; however I have never tested them out.

I think it depends on what part of Manta would contain platform specific code. What is the operation? Could the directory access be performed in python and then the results passed to Manta code?

Hi everyone,

Is it safe to use POSIX-compliant directory-reading in Manta (i.e. opendir() )?

Anyone know of different/better options?
