The keyword static does not generally affect where such variables are located it specifies their scope to be local to the current module. This is where variables, which are defined outside of functions, are located. It may be useful to think in terms of data memory in C and C++ as being divided into three separate spaces: In this session the problems will be outlined in detail and an approach to deterministic dynamic memory allocation detailed. For embedded - generally real time - applications, ignoring the issues is not an option.ĭynamic memory allocation tends to be nondeterministic the time taken to allocate memory may not be predictable and the memory pool may become fragmented, resulting in unexpected allocation failures. For desktop applications, where memory is freely available, these difficulties can be ignored. However, the handling of such dynamic memory can be problematic and inefficient. This is certainly standard practice in both languages and almost unavoidable in C++. In C and C++, it can be very convenient to allocate and de-allocate blocks of memory as and when needed.
