To put this focus on throughput in perspective, one can look at the difference between DSP memory design and memory for other microprocessors. Most microprocessors use a single memory space containing both data and instructions, using one bus for address and other for data or instructions. This a...
When an image load callback is fired, the driver checks whether the loaded image is NTDLL. If so, it resolves pointers of several functions inside NTDLL and writes them to the newly mapped section and thus resolves needed function addresses used by the bootstrap DLL. The final step is...
Manual memory management:Pointers in languages like C and C++ allow manual control and allocation of memory, which can be useful for certain applications like games and device drivers. However, for general-purpose Object-Oriented Programming (OOP), the use of pointers can introduce complexities and...
The routine that allocates the pointers is separate from the routines that assign/use them. Sorry if this confused you. RE: initialization - I'm not sure why they are not initialized. I was trying to alter the code as little as possible (under guidance of one of the agency's developers...
Thanks for the replies guys. I never really use pointers other than references so deep copying isnt something I have to worry about then. I understand whats going on with copying when using functions when you pass by value and reference, so a copy constructor does the exact same thing passin...

c. converts arrays and functions to pointers. This is usually a good-enough mental model. Ifdecaywas absent, the function might look like 1 2 3 4 template<typenameT>autof(T&& val) { T* tmp =newT{ std::forward<T>(val) };returntmp; } ...
the reputation of this year's draft class could use a boost as no player has cemented himself as the true No. 1 overall pick. However, we make the argument that this is shaping up to be a relatively deep draft class after all.Who are the prospects who could still make ...
Return value not initialized: C function does not return value when expected. Polyspace assumes that, at declaration: Variables have full-range of values allowed by their type. Pointers can beNULL-valued or point to a memory block at an unknown offset. ...
