## Detailed Description

### template\<typename \_Tp\>

class \_\_gnu\_cxx::\_\_detail::\_\_mini\_vector\< \_Tp \>"\_\_mini\_vector\<\> is a stripped down version of the full-fledged std::vector\<\>.

It is to be used only for built-in types or PODs. Notable differences are:

- 1\.

  Not all accessor functions are present.

- 2\.

  Used ONLY for PODs.

- 3\.

  No Allocator template argument. Uses operator new() to get memory, and operator delete() to free it. Caveat: The dtor does NOT free the memory allocated, so this a memory-leaking vector!
