/**
 * Internal AMXX buffer size for string retrieval.
 *
 * @note This is the buffer size AMX Mod X uses internally to retrieve strings
 *       from plugins. Most natives that take strings as arguments will
 *       implicitly truncate them to this maximum length. This has been raised
 *       to the current value with AMXX 1.8.3. Previously the limit was 3072.
 * @note This is here mainly for documentation purposes. By default plugins
 *       don't have enough memory available to allocate an array of this size.
 *       You probably should not use this to actually declare a buffer unless
 *       you *absolutely* have to. Look at #pragma dynamic to increase a plugins
 *       available memory.
