# 二、使用C语言将errno转换为描述文字
```c
#include <errno.h>
#include <string.h>
#include <stdio.h>
 
int main()
{
  int i;
  for (i = 0; i < 140; ++i)
  {
    printf("errno %d :\t\t%s\n",i,strerror(i));
  }
  return 0;
}
```

# 三、Linux终端errno转换为描述文字
Linux Shell没有专门命令转换errno，不过我们可以使用Python进行查询：
```python
[yz@MiWiFi-R4A-srv ~]$ python
>>> import os
>>> import errno
>>> print(os.strerror(11))
Resource temporarily unavailable
```
