In C language, the maximum number of threads that can be created in a process

The given task is to find the maximum number of threads that can be created in a process

C.

Threads are lightweight processes that can be managed independently by the scheduler. because of one A thread is a component of a process, so multiple threads can be associated with it

Compared to processes, threads are not only lighter to handle, but also require less time to switch contexts.

Threads require fewer resources than processes, and they also share memory with their peers.

thread. All user-level peer threads are treated as a single task by the operating system. less Their creation and termination take time.

The output is always different every time the program is executed.

The method used in the program below is as follows

• Create the function void* create(void *) and leave it empty as it is only for demonstration

• Initialize two int type variables max = 0 and ret = 0 in the main() function Store the maximum number of threads and the return value separately.

• Declare a variable "th" of type pthread_t.

• Run the while loop with condition ret == 0 and place ret = pthread_create (&th, NULL, create, NULL);

• Iterate max inside the loop.

• Print max outside the loop.

Example

#include<pthread.h>
#include<stdio.h>
/*Leave the function empty as it
only demonstrates work of thread*/
void *create ( void *){
}
//main function
int main(){
   int max = 0, ret = 0;
   pthread_t th;
   //Iterate until 0 is returned
   while (ret == 0){
      ret = pthread_create (&th, NULL, create, NULL);
      max++;
   }
   printf(" %d ", max);
}

Output

5741
