Struct Tread

pub struct Tread {
    pub fid: u32,
    pub offset: u64,
    pub count: u32,
}

read – read data from a file

size[4] Tread tag[2] fid[4] offset[8] count[4]
size[4] Rread tag[2] count[4] data[count]

read performs I/O on the file represented by fid.

Under 9P2000.L, read cannot be used on directories. See Treaddir for reading directories.

See the Plan 9 manual page for read(5).

Fields

fid: u32``offset: u64``count: u32
