	Iï¿½m trying to implement a security scheme based on groups, so I tried to
write some little functions in C. Unfortunately, although I managed to read the 
internal format, I couldnï¿½t create the ArrayType to return to the backend. It shouldnï¿½t
 be very difficult. I mean, itï¿½s only one dimension.
	I tried to use a string and array_in, too; but array_in keeps saying 
"array_in:need to specify dimension"
	Are there some functions already written to implement this kind of security.
