一个简单的C++线程示例

以下是一个简单的C线程示例：

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void *print_message_function(void *ptr);

int main()
{
pthread_t thread1, thread2;
char *message1 = "Thread 1";
char *message2 = "Thread 2";
int iret1, iret2;

iret1 = pthread_create(&thread1, NULL, print_message_function, (void*) message1);
iret2 = pthread_create(&thread2, NULL, print_message_function, (void*) message2);

pthread_join(thread1, NULL);
pthread_join(thread2, NULL);

printf("Thread 1 returns: %d\n", iret1);
printf("Thread 2 returns: %d\n", iret2);

return 0;
}

void *print_message_function(void *ptr)
{
char *message;
message = (char *) ptr;
printf("%s \n", message);
}
