Re: Get the empty space on a file system
2) knowing the file system from 1), how to check the remaining space in the file system? You normally just start writing and deal with the errors that come from full file systems when they show up. The C functions set errno accordingly. The reason is that the system lies about the remainig space. Weather there is any space left you may use, depends on the user you're running your program as. It would be kinda stupid if your program didn't work because the disk was full, even when you're running as root and are permitted to use the remaining safety space (8% by default). In my case, I am writing log files, so I would start with removing older logs to make space for the newer ones. That is why I refer to know before hand how much space is available, to allow some cleaning, rather than waiting for a problem. It seems that statfs is the answer.
