Function posish::fs::fallocate[−][src]

pub fn fallocate<Fd: AsFd>(
    fd: &Fd, 
    mode: FallocateFlags, 
    offset: u64, 
    len: u64
) -> Result<()>

Expand description

fallocate(fd, mode, offset, len)

This is a more general form of posix_fallocate, adding a mode argument which modifies the behavior. On platforms which only support posix_fallocate and not the more general form, no FallocateFlags values are defined so it will always be empty.
