以下是经过纠正的代码：

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

void *p1(void *arg) {
int i, tmp = 0;
for (i = 1; i <= 100; i++) {
tmp += i;
}
*(int *)arg += tmp;
return NULL;
}

void *p2(void *arg) {
int i, tmp = 0;
for (i = 101; i <= 200; i++) {
tmp += i;
}
*(int *)arg += tmp;
return NULL;
}

int main() {
int sum1 = 0, sum2 = 0;
pthread_t t1, t2;
void *result;
int res = pthread_create(&t1, NULL, p1, &sum1);
if (res != 0) {
perror("failed to create thread");
exit(1);
}
res = pthread_create(&t2, NULL, p2, &sum2);
if (res != 0) {
perror("failed to create thread");
exit(1);
}
res = pthread_join(t1, &result);
if (res != 0) {
perror("failed to join thread");
exit(2);
}
res = pthread_join(t2, &result);
if (res != 0) {
perror("failed to join thread");
exit(2);
}
printf("sum: %d %d\n", sum1, sum2);
return 0;
}

这段代码的功能是创建两个线程，分别计算1到100和101到200的整数的和，然后将两个和输出。在主函数中，先创建两个线程并分别执行p1和p2函数，将计算结果存储在sum1和sum2变量中。然后通过pthread_join函数等待线程执行完毕，并将结果存储在result变量中。最后将两个和输出。
