It may be useful to think in terms of data memory in C and C++ as being divided into three separate spaces: Static memory. This is where variables, which are defined outside of functions ... to ...

However, I strongly suspect that many other embedded systems could be improved by judiciously using dynamic memory allocation. In places where the standard C or C++ allocation and deallocation ...

The C/C++ runtime equivalents are malloc and new. VirtualAlloc function for direct allocation from OS. Kernel32 APIs to hold kernel memory for the app. Example, CreateFile, CreateThread.

The flags field controls the behavior of memory allocation. We can divide flags into three groups: action modifiers, zone modifiers and types. Action modifiers tell the kernel how to allocate memory.

Reserving memory for specific purposes. At startup, operating systems and applications reserve fixed amounts of memory (RAM) and may allocate more as needed. Although a virtual memory function ...

Modern operating systems perform dynamic memory allocation for their own use. They may also perform the same operation for their applications, or they may include programming interface functions ...
