bin:unpack-integer

Returns a signed integer value represented by the $size octets starting from $offset in the input binary representation. Necessary sign extension is performed (i.e. the result is negative if the high order bit is '1').

unpack-integer($in as xs:base64Binary, $offset as xs:integer, $size as xs:integer) ➔ xs:integer

Arguments
	$in	xs:base64Binary	Input binary data
	$offset	xs:integer	Offset in octets into the input data
	$size	xs:integer	The number of octets to unpack
Result		xs:integer

unpack-integer($in as xs:base64Binary, $offset as xs:integer, $size as xs:integer, $octet-order as xs:string) ➔ xs:integer

	$size	xs:integer	The number of octets to unpack
	$octet-order	xs:string	The order (most/least significant first) in which to pack or unpack octets
