// This is identical to GrB_Descriptor_set, except that the last argument is a
// pointer whose type depends on the field. For the four descriptor fields
// in the spec, the type is the same as GrB_Descriptor_set (a scalar of
// type GrB_Desc_Value).
// GxB_Desc_set is a single va_arg-based method for any descriptor option,
// of any type. The following functions are alternative methods that do not
// use va_arg (useful for compilers and interfaces that do not support va_arg):
