1874	Registry functions should return more meanginful values	anonymous		"Along with @error, @extended should tell the reason why the error occured e.g. for RegRead

{{{
Failure: Returns """" and sets the @error flag: 
1 if unable to open requested key  
	 @extended is set to 
	  1 key does not exist
	  2 read/write permission error
 2 if unable to open requested main key 
 3 if unable to remote connect to the registry 
 -1 if unable to open requested value 
	  @extended is set to 
	  1 value does not exist
	  2 value is empty
 -2 if value type not supported 
	  @extended is set to type of the value $REG_... . 
}}}

This kind of function could be more usable
{{{
Func RegExists($sKey, $sValue = """")
	Local $iReturn = RegRead($sKey, $sValue)
	If @error = 1 And @extended = 1 then Return SetError(0, 1, 0) ;key doesn't exist
	If @error = -1 And @extended = 1 then Return SetError(0, 2, 0) ; value doesnt exist
	If @error = -1 And @extended = 2  Return 1 ; empty values are fine with us
	If @error <> 0 And Return SetError(@error, @extended, $iReturn) ; an error occured
	Return 1 ; the key exists
EndFunc
