Example of the #pragma isolated_call Preprocessor Directive

The following example shows the use of the #pragma isolated_call directive. Because the function this_function does not have side effects, a call to it will not change the value of the external variable a. The argument to that_function has the value 6.

int a, this_function(int)     /* Assumed to have no side effects */

#pragma isolated_call(this_function)

that_function()
{
    a = 6;

    this_function(7);   /* Call does not change the value of "a" */
    other_function(a);  /* Argument "a" has the value of 6       */
}
