我个人阴道检查,它没有错误,有没有人有更好的主意？

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

#define THREAD_RUN 100

static char *global;

static char *x1 = "This is thread 1";

static char *x2 = "This is thread 2";

void * write(void* thr_data) {
    int n = *(int*)thr_data;

    if(n%2==0) goto RETRY1;
    else goto RETRY2;

RETRY1:
    for (n = 0; n < 1000; ++n) {
        global = x1;
    }
    goto RETRY1;


RETRY2:
    for (n = 0; n < 1000; ++n) {
        global = x2; …
