| <dl compact="compact"> |
| <dt><em>Description</em>:</dt> |
| <dd><p>This function returns <code>true</code> if nested parallel regions are |
| enabled, <code>false</code> otherwise. Here, <code>true</code> and <code>false</code> |
| represent their language-specific counterparts. |
| </p> |
| <p>Nested parallel regions may be initialized at startup by the |
| <code>OMP_NESTED</code> environment variable or at runtime using |
| <code>omp_set_nested</code>. If undefined, nested parallel regions are |
| disabled by default. |
