Detailed Description
The free list class for managing chunks of memory to be given to and returned by the bitmap_allocator.
Definition at line 521 of file bitmap_allocator.h.
Member Function Documentation
void __gnu_cxx::free_list::_M_clear ()
This function just clears the internal Free List, and gives back all the memory to the OS.
size_t* __gnu_cxx::free_list::_M_get (size_t__sz)std::bad_alloc
This function gets a block of memory of the specified size from the free list.
Parameters:
__sz The 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) [inline]
This function returns the block of memory to the internal free list.
Parameters:
__addr The pointer to the memory block that was given by a call to the _M_get function.
