在C/C++中的線程函數

在本教程中，我們將討論一個程式來理解 C/C 中的執行緒函數。

執行緒函數允許使用者同時實作並發函數，這些函數可以相互依賴用於執行或獨立。

範例

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
void* func(void* arg){
   //detaching the current thread
   pthread_detach(pthread_self());
   printf("Inside the thread\n");
   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 terminates\n");
   if(pthread_equal(ptid, pthread_self())
      printf("Threads are equal\n");
   else
      printf("Threads are not equal\n");
   //waiting for the created thread to terminate
   pthread_join(ptid, NULL);
   printf("This line will be printed" " after thread ends\n");
   pthread_exit(NULL);
}
int main(){
   fun();
   return 0;
}

輸出

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