在C/C++中的线程函数

在本教程中，我们将讨论一个程序来理解 C/C++ 中的线程函数。

线程函数允许用户同时实现并发函数，这些函数可以相互依赖用于执行或独立。

示例

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
void* func(void* arg){
   //detaching the current thread
   pthread_detach(pthread_self());
   printf("Inside the threadn");
   pthread_exit(NULL);
}
void fun(){
   pthread_t ptid;
   //creating a new thread
   pthread_create(&ptid, NULL, &func, NULL);
   printf("This line may be printed before thread terminatesn");
   if(pthread_equal(ptid, pthread_self())
      printf("Threads are equaln");
   else
      printf("Threads are not equaln");
   //waiting for the created thread to terminate
   pthread_join(ptid, NULL);
   printf("This line will be printed" " after thread endsn");
   pthread_exit(NULL);
}
int main(){
   fun();
   return 0;
}

输出

This line may be printed before thread terminates
Threads are not equal
Inside the thread
This line will be printed after thread ends
