		int *	array_id
	)

osl_scop_get_attributes function: this function returns, through its parameters, the maximum values of the relation attributes (nb_iterators, nb_parameters etc) in the scop. HOWEVER, it updates the parameter value iff the attribute is greater than the input parameter value. Hence it may be used to get the attributes as well as to find the maximum attributes for several scop lists. The array identifier 0 is used when there is no array identifier (AND this is OK), OSL_UNDEFINED is used to report it is impossible to provide the property while it should. This function is not intended for checking, the input scop should be correct.

Parameters:

[in]	scop	The scop to extract attributes values.
[in,out]	nb_parameters	Number of parameter attribute.
[in,out]	nb_iterators	Number of iterators attribute.
[in,out]	nb_scattdims	Number of scattering dimensions attribute.
[in,out]	nb_localdims	Number of local dimensions attribute.
[in,out]	array_id	Maximum array identifier attribute.
