A.31 Thread-Safe Lock Functions

 

The following C++ example demonstrates how to initialize an array of locks in a parallel region by using omp_init_lock (Section 3.2.1 on page 42).

Example

Code

// A_13_omp_init_lock.cpp  
// compile with: /openmp  
#include <omp.h>  
  
omp_lock_t *new_locks() {  
   int i;  
   omp_lock_t *lock = new omp_lock_t[1000];  
   #pragma omp parallel for private(i)  
   for (i = 0 ; i < 1000 ; i++)  
      omp_init_lock(&lock[i]);  
  
   return lock;  
}  
  
int main () {}
