HarmonyOS fopen打开文件失败

代码如下：

FILE *fpkt = NULL;
if(fpkt == NULL) {
  fpkt = fopen("/storage/media/100/local/files/Docs/tina/pkt.h265", "w+");
  if(fpkt == NULL)
    ALOGI("tinatest error fopen %d\n", errno);
}

报错打印如下：

F     tinatest error fopen 2

使用hdc命令进行文件读取，确认该文件路径无误

hdc file recv /storage/media/100/local/files/Docs/tina/pkt.h265 ~/Desktop
