Struct native::io::file::FileDesc[src]

pub struct FileDesc {
    // some fields omitted
}

Methods

impl FileDesc

fn new(fd: fd_t, close_on_drop: bool) -> FileDesc

Create a FileDesc from an open C file descriptor.

The FileDesc will take ownership of the specified file descriptor and close it upon destruction if the close_on_drop flag is true, otherwise it will not close the file descriptor when this FileDesc is dropped.

Note that all I/O operations done on this object will be blocking, but they do not require the runtime to be active.
