IO::readable

Public Instance Methods

sysread(integer[, outbuf]) → string click to toggle source

Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

 
               static VALUE
strio_sysread(int argc, VALUE *argv, VALUE self)
{
    VALUE val = rb_funcall2(self, rb_intern("read"), argc, argv);
    if (NIL_P(val)) {
        rb_eof_error();
    }
    return val;
}
readbyte → fixnum click to toggle source

See IO#readbyte.

 
               static VALUE
strio_readbyte(VALUE self)
{
    VALUE c = rb_funcall2(self, rb_intern("getbyte"), 0, 0);
    if (NIL_P(c)) rb_eof_error();
    return c;
}
readchar → string click to toggle source

See IO#readchar.

 
               static VALUE
strio_readchar(VALUE self)
{
    VALUE c = rb_funcall2(self, rb_intern("getc"), 0, 0);
    if (NIL_P(c)) rb_eof_error();
    return c;
}
readline(sep=$/) → string click to toggle source
readline(limit) → string or nil
readline(sep, limit) → string or nil

See IO#readline.

 
               static VALUE
strio_readline(int argc, VALUE *argv, VALUE self)
{
    VALUE line = rb_funcall2(self, rb_intern("gets"), argc, argv);
    if (NIL_P(line)) rb_eof_error();
    return line;
}
