Extent

These utilities are for handling extents (arrays and pointers) in C and C++.

ZTD_PTR_EXTENT(...)

Provides the T arg[static N] functionality (“sized at least `N` large” hint).

Remark

Expands to the proper notation for C compilers, and expands to nothing for C++ compilers. It is meant to be used as in the declaration: void f(T arg[ZTD_PTR_EXTENT(N)]);.

Parameters

• ... – [in] An expression which computes the intended size of the pointer argument.
