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

The omp_get_thread_num function returns the thread number, within its team, of the thread executing the function. The thread number lies between 0 and omp_get_num_threads()–1, inclusive. The master thread of the team is thread 0.

The format is as follows:

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

If called from a serial region, omp_get_thread_num returns 0. If called from within a nested parallel region that is serialized, this function returns 0.
