-
#read_nonblock(integer[, outbuf [, opts]]) ⇒ String
Similar to

, but raisesEOFError
at end of string unless the exception: false option is passed in. -
#readbyte ⇒ Fixnum
See
IO#readbyte
. -
#readchar ⇒ String
See
IO#readchar
. -
#readline(sep = $/) ⇒ String

. -
#readpartial(integer[, outbuf]) ⇒ String
Alias for #sysread.
-
#sysread(integer[, outbuf]) ⇒ String
(also: #readpartial)
Similar to
#read
, but raisesEOFError
at end of string instead of returningnil
, as well asIO#sysread
does.
