例如 _sopen_s 在磁盘空间不够的时候，宏 errno 就会返回 ENOSPC（28）

MSDN 文档时只提到以下错误码

errno value	Condition
EACCES	The given path is a directory, or the file is read-only, but an open-for-writing operation was attempted.
EEXIST	_O_CREAT and _O_EXCL flags were specified, but filename already exists.
EINVAL	Invalid oflag, shflag, or pmode argument, or pfh or filename was a null pointer.
EMFILE	No more file descriptors available.
ENOENT	File or path not found.
