The following example demonstrates the reprivatization of variables. Private variables can be marked private again in a nested directive. They do not have to be shared in the enclosing parallel region.

int i, a;  
...  
#pragma omp parallel private(a)  
{  
  ...  
  #pragma omp parallel for private(a)  
  for (i=0; i<10; i++)  
     {  
       ...  
     }  
}
