先决条件：C语言中的多线程
语法：-pthread_t pthread_self(void);
pthread_self()函数返回在其中调用该线程的ID。
// C program to demonstrate working of pthread_self()
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
void* calls(void* ptr)
{
// using pthread_self() get current thread id
printf("In function \nthread id = %d\n", pthread_self());
pthread_exit(NULL);
return NULL;
}
int main()
{
pthread_t thread; // declare thread
pthread_create(&thread, NULL, calls, NULL);
printf("In main \nthread id = %d\n", thread);
pthread_join(thread, NULL);
return 0;
}
输出：
In function thread id = 1 In main thread id = 1
