C - Mutex attributes -

can create , use 1 mutex attribute initialize multiple recursive mutexes? or have create 1 mutex attribute each mutex want create? following code correct?

int err; int bufferlength = 10; pthread_mutexattr_t recursiveattr; pthread_mutex_t mutexes[bufferlength];  for(int index = 0; index < bufferlength; index++){     err = pthread_mutex_init(&mutexes[i], &recursiveattr);     if(err != 0){         perror("error initializing mutex");     } } 

you can use same attribute object multiple mutexes.

note however, pthread_mutexattr_t object you're using must initialized itself. initialize pthread_mutexattr_t must use pthread_mutexattr_init (and eventually, pthread_mutexattr_destroy), both of should done once. current code makes no such calls, , should compliant.
