Read the arguments to VirtualAlloc() in the question again: the two allocations use two different ranges of pages. I'm having a similar problem, where code that walks the virtual space calling VirtualAlloc() with specific base addresses fails to find *any* allocatable space within a 1 GB ...
Syntax ofmalloc: void*malloc(size_t size); Parameters: size: Specifies the number of bytes to allocate in memory. Return Type: void*: It returns a void pointer (void*) that can be implicitly cast to any other pointer type. This pointer points to the allocated memory block. ...
In this example, firstly, we allocated the memory using the new operator, then deallocated it using the delete operator. Click here to check the working of the code as mentioned above. Allocate and Deallocate the Memory Using C Standard Library Using malloc(), free(), and realloc(), the ...
You can also detect symbols like __WIN32__ to detect if you are in a Windows build environment. Some compilers will define __unix__ or __APPLE__ if your build environment is of that variety.Or for gcc you can use something like this:...

There is no need to copy the data between the host and the device. float *d_A = static_cast<float*>(malloc_shared(size, queue)); You can also use different memory allocation methods by coping the data from: The host to the device The device to the host c. Queue Submit To define...
I was looking for a tutorial/book that would teach me how to start to use FFmpeg as a library (a.k.a. libav) and then I found the "How to write a video player in less than 1k lines" tutorial. Unfortunately it was deprecated, so I decided to write this one....
The second parameter,idclass, represents a container that has the capacity of 1, 2, or 3 integers. One alternative for theidclass is to use theitemclass which provides the programmer with more control for queries. It is an encapsulation of the execution range of the kernel and the ...
In many cases, you'll need to use Eigen::Ref "to avoid stupid copies of the arguments." (quote from the link). Integration into larger code bases To automate things and avoid having to write Eigen::internal::set_is_malloc_allowed(...) all the time, I have the piece of code below...
