3.2.11  omp_get_nested

SummaryThe deprecated omp_get_nested routine returns whether nested parallelism is enabled or disabled, according to the value of the max-active-levels-var ICV.

Format

 
int omp_get_nested(void);
  

 
logical function omp_get_nested()
  

BindingThe binding task set for an omp_get_nested region is the generating task.

EffectThis routine returns true if max-active-levels-var is greater than 1 for the current task; it returns false, otherwise. If an implementation does not support nested parallelism, this routine always returns false. This routine has been deprecated.
