Classes
struct	ein::c_munmap
	std::unique_ptr Deleter for memory mapped data More...
struct	ein::c_free
	std::unique_ptr Deleter that calls free() More...

Namespaces
namespace	ein

Concepts
concept	ein::trivially_destructible
	a type where the destructor does no work, and therefore it is safe to simply discard.

Typedefs
using	ein::mmap_ptr = std::unique_ptr<void,c_munmap>
	memory mapped data, managed by std::unique_ptr. calls munmap to free.
template<trivially_destructible T>
using	ein::unique_c_ptr = std::unique_ptr<T, c_free>
	a unique_ptr managed c pointer, deleted by free()
using	ein::unique_str = unique_c_ptr<char const>
	a c string, managed by unique_ptr

Functions
mmap_ptr	ein::make_mmap_ptr (void *p, size_t size) noexcept
	construct a mmap_ptr using a base pointer and its size for munmap
unique_str	ein::dup (char const *str) noexcept
	duplicate a C string using strdup and manage it as a unique_str
