Hi folks,
got a couple of questions about using shared memory allocators. Please see
below.
I have the following code
template <typename T> using CAP_Alloc = cached_adaptive_pool<T,
segment_manager_t>; using CAP_Shmem_String = basic_string<char,
std::char_traits<char>, CAP_Alloc<char> >;
using CAP_Shmem_String_Alloc = CAP_Alloc<CAP_Shmem_String>;
using CAP_Shmem_Void_Alloc = CAP_Alloc<void>;
class MyDataBlock{
using pointer = CAP_Shmem_String_Alloc::pointer;
pointer strData; float extraData;
MyDataBlock(): strData(nullptr), extraData(0.0) {} MyDataBlock(const
CAP_Shmem_Void_Alloc& alloc) { /* My question is how do I
convert CAP_Shmem_Void_Alloc to type CAP_Shmem_String_Alloc to call allocate?
And do I pass in the void allocator as a construction argument? Is there a
difference between allocate and construct?
*/
}
~MyDataBlock() { /* To delete the memory, do I need to
keep around a copy of the original allocator, so I can call deallocate or
destroy? Or can that be derived or converted from somewhere, like calling
strData->alloc() ?
*/
}
}
Any help would be greatly appreciated.
Thank you.
