void omp_set_num_threads (intnum_threads); Parameters num_threads Must be a positive integer. Usage If thenum_threadsclause is present, then for the parallel region it is applied to, it supersedes the number of threads requested by this function or theOMP_NUM_THREADSenvironment variable. Subs...
The omp_set_num_threads routine specifies the number of threads to use for the next parallel region by setting the first value of num_list for the OMP_NUM_THREADS environment variable. The number_of_threads_expr argument is evaluated, and its value is used as the number of threads. If ...

Hello from thread0 如果我改为使用以下内容: 1 2 3 4 5 6 7 omp_set_num_threads(4); #pragma omp parallel //num_threads(4) { inti=omp_get_thread_num(); printf_s("Hello from thread %d\ ", i); } 输出是 1 2 3 4 5 6
