size_t* __gnu_cxx::free_list::_M_get ( size_t  __sz)
throw (std::bad_alloc
)

This function gets a block of memory of the specified size from the free list.

Parameters
__szThe size in bytes of the memory required.
Returns
A pointer to the new memory block of size at least equal to that requested.
void __gnu_cxx::free_list::_M_insert ( size_t *  __addr)
throw (
