I'm trying to create a graph of the distribution of file sizes on my ext4 system. I'm trying to write a script to scrape this information from my computer somehow. I don't care where the files are stored in the directory structure, only how much space each takes up. I know file sizes are stored in the inode metadata, and it seems like it might be pretty fast to read through the inode table, if such a thing exists. Does anyone know of a C API for accessing the size of files, or reading directly from the inode table? Does anyone know where the inode table is stored?
If you want a C API, you're going to end up with GNU
