Dir#seek

seek(position) → self

static VALUE
dir_seek(VALUE dir, VALUE pos)
{
    struct dir_data *dirp;
    long p = NUM2LONG(pos);

    GetDIR(dir, dirp);
    seekdir(dirp->dir, p);
    return dir;
}

Sets the position in self and returns self. The value of position should have been returned from an earlier call to tell; if not, the return values from subsequent calls to read are unspecified.

See Dir As Stream-Like.

Examples:

Example

dir = Dir.new('example')
dir.pos      # => 0
dir.seek(3)  # => #<Dir:example>
dir.pos      # => 3
dir.seek(30) # => #<Dir:example>
dir.pos      # => 5
