Global Variables

Globally declared variables are allocated in the data segment of a process; updates performed by a thread on one process are therefore not visible on other processes. However, any global variables declared and initialized by the C++ program before the start of the RT++ program are visible in the same way to all RT++ threads provided that these variables are not modified during the execution of the RT++ program.
