Detailed Description

template<typename T, std::enable_if_t< std::is_integral_v< T >, bool > = true>
struct jau::callocator_sec< T, >

A simple secure allocator for integral types using POSIX C functions: ::malloc() and ::free().

callocator_sec is similar to callocator, but

This class shall be compliant with C++ named requirements for Allocator.

Not implementing deprecated (C++17) and removed (C++20) methods: address(), max_size(), construct() and destroy().
