pub fn raw_read_listing(path: &Path) -> Result<Vec<u8>>Expand description
The whole contents of the procfs listing at path, read with raw
syscalls and without allocating between reads, so that where the tool
shares the guest’s process its own allocator maps nothing while the
kernel walks the address space: the buffer is allocated before the first
read, and a listing that fills it is read again, from the start, into one
twice the size.
