Detailed Description

template<typename Type>
struct std::allocator< Type >

The "standard" allocator, as per [20.4].

The private Alloc is "SGI" style. (See comments at the top of stl_alloc.h.)

The underlying allocator behaves as follows.

• __default_alloc_template is used via two typedefs
• "single_client_alloc" typedef does no locking for threads
• "alloc" typedef is threadsafe via the locks
• new_alloc is used for memory requests

(See allocators info for more.)
