Homebrew ctrulib get name and path of current 3dsx

[mashers]

Is there any way for ctrulib to identify the name and full path of the currently running 3dsx? I want gridlauncher to be able to find its own executable on the SD card.

Is it not argv[0]? Dunno if entrypoints bother setting up an initial argc/argv, though.

Yeah, take a look at the romfs code:

https://github.com/smealum/ctrulib/blob/master/libctru/source/romfs_dev.c#L119

For 3dsx romfs support, it has to open itself for reading (the romfs is embedded in the 3dsx), and that code handles it.

I don't know if the entry points set it up, but the hb launcher's main() doesn't specify any parameters so I assume none are passed.

Thank you, I'll look at this

I just tried it, and yeah, themehax at least doesn't seem to push any arguments to regular argv. I guess it makes sense, since a boot.3dsx wouldn't really need arguments in the first place. Maybe Cruel's idea will work.
