}
Similar to read, but raises EOFError
at end of string unless the +exception: false+ option is passed in.

static VALUE
strio_sysread(int argc, VALUE *argv, VALUE self)
{
VALUE val = rb_funcallv_kw(self, rb_intern("read"), argc, argv, RB_PASS_CALLED_KEYWORDS);
if (NIL_P(val)) {
rb_eof_error();
}
return val;
}
Similar to read, but raises EOFError
at end of string instead of returning nil
, as well as IO#sysread
does.
