3.1.10 omp_get_nested Function

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The omp_get_nested function returns a nonzero value if nested parallelism is enabled and 0 if it is disabled. For more information on nested parallelism, see Section 3.1.9 on page 40. The format is as follows:

#include <omp.h>  
int omp_get_nested(void);  

If an implementation does not implement nested parallelism, this function always returns 0.
