Call Reentrant Code in a Multithreaded Environment - MATLAB & Simulink (original) (raw)

Main Content

To call reentrant code, create a main function that:

• Includes the header file _primaryfunctionname_.h.
• For each thread, allocates memory for the global memory allocation structure _primaryfunctionname_ StackData.
• If the algorithm uses persistent or global data, allocates memory for the global structure_primaryfunctionname_ PersistentData. If the threads communicate, allocate this memory once for the root process. Otherwise, you can allocate memory per thread.
• Contains a thread function that calls these functions:
  • _primaryfunctionname_ _initialize.
  • _primaryfunctionname_.
  • _primaryfunctionname_ _terminate.
    When you convert a MATLAB® function to a C/C++ library function or a C/C++ executable,MATLAB Coder™ generates two housekeeping functions. Call these functions in the code that calls the generated C/C++ function. For more information, seeDeploy Generated Code.
• Initializes each thread and passes in a pointer to the memory allocation structure as the first parameter to the thread function.
• Frees up the memory used for global structures.
