//
// - Override these routines from the CRT by redefining them. By default we wrap
// the CRT functions from <strings.h> and <math.h>, e.g:
//
// #define DQN_MEMCPY(dest, src, count) memcpy(dest, src, value)
// #define DQN_MEMSET(dest, value, count) memset(dest, value, count)
// #define DQN_MEMCMP(lhs, rhs, count) memcpy(lhs, rhs, count)
// #define DQN_MEMMOVE(dest, src, count) memmove(dest, src, count)
// #define DQN_SQRTF(val) sqrtf(val)
// #define DQN_SINF(val) sinf(val)
// #define DQN_COSF(val) cosf(val)
// #define DQN_TANF(val) tanf(val)
//
// - Redefine 'DQN_API' to change the prefix of all declared functions in the library
//
// #define DQN_API
//
// - Define 'DQN_STATIC_API' to apply 'static' to all function definitions and
// disable external linkage to other translation units by redefining 'DQN_API' to
// 'static'.
//
// #define DQN_STATIC_API
//
// - Turn all assertion macros to no-ops except for hard asserts (which are
// always enabled and represent unrecoverable errors in the library).
//
// #define DQN_NO_ASSERT
//
// - Augment DQN_CHECK(expr) macro's behaviour. By default when the check fails a
// debug break is emitted. If this macro is defined, the check will not trigger
// a debug break.
//
// #define DQN_NO_CHECK_BREAK
//
// - Define this macro to enable memory leak tracking on arena's that are
// configured to track allocations.
//
// Allocations are stored in a global hash-table and their respective stack
// traces for the allocation location. Memory leaks can be dumped at the end
// of the program or some epoch by calling Dqn_Library_DumpLeaks()
//
// #define DQN_LEAK_TRACKING
//
// - Define this to revert to the family of printf functions from <stdio.h>
// instead of using stb_sprintf in this library. stb_sprintf is 5-6x faster
// than printf with a smaller binary footprint and has deterministic behaviour
// across all supported platforms.
//
// #define DQN_USE_STD_PRINTF
//
// However, if you are compiling with ASAN on MSVC, MSVC's implementation of
// __declspec(no_sanitize_address) is unable to suppress warnings in some
// individual functions in stb's implementation causing ASAN to trigger. This
// library will error on compilation if it detects this is the case and is
// being compiled with STB sprintf.
//
// - Define this to stop this library from defining a minimal subset of Win32
// prototypes and definitions in this file. You should use this macro if you
// intend to #include <Windows.h> yourself to avoid symbol conflicts with
// the redefined declarations in this library.
//
// #define DQN_NO_WIN32_MIN_HEADER
//
// - Define this to stop this library from defining STB_SPRINTF_IMPLEMENTATION.
// Useful if another library uses and includes "stb_sprintf.h"
//
// #define DQN_STB_SPRINTF_HEADER_ONLY
//
// - Override the default break into the active debugger function. By default
// we use __debugbreak() on Windows and raise(SIGTRAP) on other platforms.
//
// #define DQN_DEBUG_BREAK
//
// - Define this macro to 1 to enable poisoning of memory from arenas when ASAN
// `-fsanitize=address` is enabled. Enabling this will detect memory overwrite
// by padding allocated before and after with poisoned memory which will raise
// a use-after-poison in ASAN on read/write. This is a no-op if the library is
// not compiled with ASAN.
//
// #define DQN_ASAN_POISON 1
//
// - Define this macro 1 to enable sanity checks for manually poisoned memory in
// this library when ASAN `-fsanitize=address` is enabled. These sanity checks
// ensure that memory from arenas are correctly un/poisoned when pointers are
// allocated and returned to the memory arena's. This is a no-op if we are not
// compiled with ASAN or `DQN_ASAN_POISON` is not set to `1`.
//
// #define DQN_ASAN_VET_POISON 1
//
// - Define this macro to the size of the guard memory reserved before and after
// allocations made that are poisoned to protect against out-of-bounds memory
// accesses. By default the library sets the guard to 128 bytes.
//
// #define DQN_ASAN_POISON_GUARD_SIZE 128
