* call-seq:
* IO.read(name, [length [, offset]] ) -> string
* IO.read(name, [length [, offset]], open_args) -> string
* IO.read(name, [length [, offset]] [, opt] ) -> string
*
* Opens the file, optionally seeks to the given +offset+, then returns
* +length+ bytes (defaulting to the rest of the file). <code>read</code>
* ensures the file is closed before returning.
*
* If the last argument is a hash, it specifies option for internal
* open(). The key would be the following. open_args: is exclusive
* to others.
* === Options
*
* The options hash accepts the following keys:
*
* encoding::
* string or encoding
*
* specifies encoding of the read string. +encoding+ will be ignored
* if length is specified.
* Specifies the encoding of the read string. +encoding:+ will be ignored
* if +length+ is specified. See Encoding.aliases for possible encodings.
*
* mode::
* string
*
* specifies mode argument for open(). It should start with "r"
* otherwise it will cause an error.
* Specifies the mode argument for open(). It must start with an "r"
* otherwise it will cause an error. See IO.new for the list of possible
* modes.
*
* open_args:: array of strings
* open_args::
* array of strings
*
* specifies arguments for open() as an array.
* Specifies arguments for open() as an array. This key can not be used
* in combination with either +encoding:+ or +mode:+.
*
* Examples:
*
* IO.read("testfile") #=> "This is line one\nThis is line two\nThis is line three\nAnd so on...\n"
* IO.read("testfile", 20) #=> "This is line one\nThi"
* IO.read("testfile", 20, 10) #=> "ne one\nThis is line "
* IO.read("binfile", mode: "rb") #=> "\xF7\x00\x00\x0E\x12"
