errno --- 标准 errno 系统符号¶
本模块提供标准的 errno 系统符号。每个符号的值是其对应的整数值。符号的名称和描述来自 linux/include/errno.h,应该是非常全面的。
-
errno.errorcode¶ 提供从 errno 值到底层系统中字符串名称的映射的字典。例如,
errno.errorcode[errno.EPERM]映射为'EPERM'。
如果要将数字的错误代码转换为错误信息,请使用 os.strerror()。
在下面的列表中,当前平台上没有使用的符号没有被本模块定义。 已定义的符号的具体列表可参见 errno.errorcode.keys()。 可用的符号包括:
-
errno.EPERM¶ Operation not permitted
-
errno.ENOENT¶ No such file or directory
-
errno.ESRCH¶ No such process
-
errno.EINTR¶ Interrupted system call.
