linux pthread问题
程序代码：#include <stdio.h>
#include <pthread.h>
#include <unistd.h>
#include <stdlib.h>
void pthread_run()
{
int i;
for( i = 0; i < 3; i++ )
{
printf("this is a pthread\n");
}
}
int main()
{
pthread_t id;
int i;
int ret;
ret = pthread_create(&id, NULL, (void *)pthread_run, NULL );
if( ret )
{
printf("pthread create error!!");
exit(1);
}
for( i = 0; i < 3; i++ )
printf("this is main thread\n");
pthread_join( id, NULL );
return (0);
}
这是一个简单的pthread程序，编译通过，运行的时候按道理说应该是“this is main thread”和“this is a pthread”乱序输出的，结果多次试验都是先输出三遍this is main thread，然后再输出this is a pthread，这是为什么？
