Hmmm ok in my understanding C_SIZEOF can only be used on a derived type that has bind (c) which precludes allocable and pointer components etc so you would think C_SIZEOF of is in-fact a constant expression that can be determined as compile time for but non-bind (c) DT this may not be true. size_t is defined by the C standard to be the unsigned integer return type of the sizeof operator (C99 6.3.5.4.4), and the argument of malloc and friends (C99 7.20.3.3 etc). The actual range is set such that the maximum (SIZE_MAX) is at least 65535 (C99 7.18.3.2). However, this doesn't let us determine sizeof (size_t). pooh new adventures
