* If C++ and C++ static constructors are supported, then this function

* initialization of the static C++ class instances.

* This function should then be called in the application-specific

* user_start logic in order to perform the C++ initialization. NOTE

* that no component of the core NuttX RTOS logic is involved; This
|
||||
* function definition only provides the 'contract' between application
|
||||
* specific C++ code and platform-specific toolchain support
