IO::generic_readable
Public Instance Methods
read_nonblock(integer[, outbuf [, opts]]) → string
click to toggle source
Similar to read, but raises EOFError at end of string unless
the +exception: false+ option is passed in.
static VALUE
strio_read_nonblock(int argc, VALUE *argv, VALUE self)
{
VALUE opts = Qnil, val;
rb_scan_args(argc, argv, "11:", NULL, NULL, &opts);
if (!NIL_P(opts)) {
argc--;
}
val = strio_read(argc, argv, self);
if (NIL_P(val)) {
if (!NIL_P(opts) &&
rb_hash_lookup2(opts, sym_exception, Qundef) == Qfalse)
return Qnil;
else
rb_eof_error();
}
return val;
}
readbyte → fixnum
click to toggle source
See IO#readbyte.
static VALUE
strio_readbyte(VALUE self)
{
VALUE c = rb_funcallv(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_funcallv(self, rb_intern("getc"), 0, 0);
if (NIL_P(c)) rb_eof_error();
return c;
}
readline(sep=$/, chomp: false) → string
click to toggle source
readline(limit, chomp: false) → string or nil
readline(sep, limit, chomp: false) → string or nil
See IO#readline.
static VALUE
strio_readline(int argc, VALUE *argv, VALUE self)
{
VALUE line = rb_funcallv_kw(self, rb_intern("gets"), argc, argv, RB_PASS_CALLED_KEYWORDS);
if (NIL_P(line)) rb_eof_error();
return line;
}
readpartial(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_funcallv_kw(self, rb_intern("read"), argc, argv, RB_PASS_CALLED_KEYWORDS);
if (NIL_P(val)) {
rb_eof_error();
}
return val;
}
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_funcallv_kw(self, rb_intern("read"), argc, argv, RB_PASS_CALLED_KEYWORDS);
if (NIL_P(val)) {
rb_eof_error();
}
return val;
