Hi everybody,

I am trying to measure the time a mutex take to lock and unlock , here is my code

*****************************************************
void *functionA();

int main(int argc, char *argv[]) {
	
	/* initialize mutex1 */
	pthread_mutex_init(&mutex1, NULL);
	
	/* create threads */
	pthread_create(&tid_A, NULL, &functionA ,NULL);
	
	/* 2 secs sleep */
	sleep(2);
}

void *functionA(){
	pthread_mutex_lock(&mutex1);
	pthread_mutex_unlock(&mutex1);
}
*******************************************************

I build the application with the IDE and at Build Options i choosed , build for profiling (Function Instrumentation)

Then i create a new run configuration for the _g binary adding the appropriate Application Profiler tool on Tools bar of
 the Open Run dialog.

I can get results for the function main and functionA but not for pthread_mutex_lock,pthread_mutex_unlock. Is it 
possible to get the time for each line of code ?
The Functon Instrumentation mode is good for single thread application what about add more threads on the above code ? 
Will i get correct results or should i do a different profile ?

thanks
