pub fn memfd_create(name: &CStr, flags: MemFdCreateFlag) -> Result<OwnedFd>Expand description
Creates an anonymous file that lives in memory, and return a file-descriptor to it.
The file behaves like a regular file, and so can be modified, truncated, memory-mapped, and so on. However, unlike a regular file, it lives in RAM and has a volatile backing storage.
