//
// This is the EASTL configuration file. All configurable parameters of EASTL
// are controlled through this file. However, all the settings here can be
// manually overridden by the user. There are three ways for a user to override
// the settings in this file:
//
//     - Simply edit this file.
//     - Define EASTL_USER_CONFIG_HEADER.
//     - Predefine individual defines (e.g. EASTL_ASSERT).
//
///////////////////////////////////////////////////////////////////////////////




///////////////////////////////////////////////////////////////////////////////
// EASTL_USER_CONFIG_HEADER
//
// This allows the user to define a header file to be #included before the
// EASTL config.h contents are compiled. A primary use of this is to override
// the contents of this config.h file. Note that all the settings below in
// this file are user-overridable.
//
// Example usage:
//     #define EASTL_USER_CONFIG_HEADER "MyConfigOverrides.h"
//     #include <EASTL/vector.h>
//
///////////////////////////////////////////////////////////////////////////////

#ifdef EASTL_USER_CONFIG_HEADER
	#include EASTL_USER_CONFIG_HEADER
#endif



///////////////////////////////////////////////////////////////////////////////
// EASTL_EABASE_DISABLED
//
// The user can disable EABase usage and manually supply the configuration
// via defining EASTL_EABASE_DISABLED and defining the appropriate entities
// globally or via the above EASTL_USER_CONFIG_HEADER.
//
// Example usage:
//     #define EASTL_EABASE_DISABLED
//     #include <EASTL/vector.h>

///////////////////////////////////////////////////////////////////////////////
// EASTL_VERSION
//
// We more or less follow the conventional EA packaging approach to versioning
// here. A primary distinction here is that minor versions are defined as two
// digit entities (e.g. .03") instead of minimal digit entities ".3"). The logic
// here is that the value is a counter and not a floating point fraction.
// Note that the major version doesn't have leading zeros.
//
// Example version strings:
//      "0.91.00"   // Major version 0, minor version 91, patch version 0.
//      "1.00.00"   // Major version 1, minor and patch version 0.
//      "3.10.02"   // Major version 3, minor version 10, patch version 02.
//     "12.03.01"   // Major version 12, minor version 03, patch version
//
// Example usage:
//     printf("EASTL version: %s", EASTL_VERSION);
//     printf("EASTL version: %d.%d.%d", EASTL_VERSION_N / 10000 % 100, EASTL_VERSION_N / 100 % 100, EASTL_VERSION_N % 100);

// this system allows you to configure it to use whatever system you want,
// provided your system meets the requirements of this library.
// The requirements are:
//
//     - Must be constructable via a const char* (name) parameter.
//       Some uses of allocators won't require this, however.
//     - Allocate a block of memory of size n and debug name string.
//     - Allocate a block of memory of size n, debug name string,
//       alignment a, and offset o.
//     - Free memory allocated via either of the allocation functions above.
//     - Provide a default allocator instance which can be used if the user
//       doesn't provide a specific one.
