Allocates a temporary buffer.

Parameters

__len

The number of objects of type Tp.

Returns

See full description.

Reinventing the wheel, but this time with prettier spokes!

This function tries to obtain storage for __len adjacent Tp objects. The objects themselves are not constructed, of course. A pair<> is returned containing the buffer s address and capacity (in the units of sizeof(_Tp)), or a pair of 0 values if no storage can be obtained. Note that the capacity obtained may be less than that requested if the memory is unavailable; you should compare len with the .second return value.

Provides the nothrow exception guarantee.

The companion to get_temporary_buffer().

Parameters

__p	A buffer previously allocated by get_temporary_buffer.

Returns

None.

Frees the memory pointed to by __p.

This class is used in two places: stl_algo.h and ext/memory, where it is wrapped as the temporary_buffer class. See temporary_buffer docs for more notes.

As per Table mumble.

Returns the size requested by the constructor; may be >size().

As per Table mumble.

As per Table mumble.

Constructs a temporary buffer of a size somewhere between zero and the size of the given range.
